So an easy one: "You guys, sold your soul to the evil just for $$$"
If it was the reason then we would have been really stupid 
Allegorithmic would have gained (a lot more) value just by waiting 1 or 2 years.
+ we have received a lot of offers in 2018 (investment funds, other companies): we just chose it because of it the best option regarding of the goals we want to achieve.
So cash was low in the list, regarding the decision to join Adobe (sorry I have to go: my private jet is waiting for me to go to Ibiza)
This doesn't help. The reason? Simple. On page 2 you admit that the sale to Adobe is for a "legally undisclosed number". Furthermore Jerc also dropped this in another thread, he said and I quote "Allegorithmic was too attracted to the financial backing Adobe can bring to the table."
So this mixed messaging is doing you no favors, especially now that the community is more or less on guard due to Adobe worming its way into the picture. One cannot say it was not about the money at this point based on those to comments alone. If you sell out, you sell out, regardless of the reasons. Granted, I think Allegoritmic's reasons might be different than a quick "get rich" scheme, but it still involves caving in and giving away the IP to a corporate entity for the sake of financial backing.
For many of us, this move was unnecessary. You don't need a massive team and high cost offices with massive bills to pay in order to "innovate" and develop great software. Many other independent studios have done this with as little as 1 to 2 highly skilled developers. The Affinity team which competes with Photoshop and Designer only has between 13-16, 3D Coat has 1 primary developer and some helpers...
...Thus many can only take an educated guess as to why Allegorithmic went with Adobe. Either its because Allego was impatient to get to their perceived finish line and took what appears to be an "easy route", or the offer to play in the "big league" was too attractive, thus the sale was also a mix of a "job offers" for a higher profile company. Both come across as developer centric decisions (whats in their own best interest) as opposed to whats in the best interest of the end user.
A reminder, a lot of the willingness to buy into and support Allegorithmic's products, to help give them the financial backing to keep going, had a lot more to do with the fact you were NOT Adobe, and could grow up to compete with them, rather than just the product itself. I think you guys over at Allego believe it was just because you made a great product, that really isnt the case. Obviously you need a decent product sell, but a lot of people were also buying into the potential of the said product. Potential includes not being part of Adobe's lineup. So in that sense, it really does look like a kind of betrayal to some users. Buying products in this industry is in part a kind of user investment into its future. If at any point you say "our ultimate goal is to sell to adobe/autodesk", then that user support will largely vanish.
Whats the point of starting new companies and supporting them if they are just going to turn over and sell to the giants that are hated? You see where we are coming from? Allegorithmic, rather Adobe, will probably never get to the point where you guys are going to be accepted now. The close knit, community trust factor, is largely going to diminish.
You guys might not even like how the corporate structure changes who you were, and will end up leaving and moving on to something else, much like what we saw with Luxology turning into Foundry. Everyone went in with high expectations and hated the stiffling corporate culture that creeped in. There is that sense that you can go in and change everything from the inside, but in reality its the opposite. It changes you. At the end of the day, your own IP is no longer in your hands and you just don't want to be a part of it anymore. If someone calls you guys "naive", it would most likely be based on that understanding of how this all plays out.
Anyways... as for as where to go from here (positive feedback). I highly recommend doing everything in your power to remain, at least on the surface, visibly, as independent from Adobe as possible. Keep the Allegorithmic branding, separate yourselves from CC, treat the products as a subsidiary rather than part of Adobe's main lineup, otherwise the affiliation to Adobe alone will be a major deterring factor. Too many of us will not, ever, install CC (not anymore). This is in everyone's best interest, yours, Allegorithmics...and Adobes.
Cheers
Add: Also want to point out that the concerns over perpetual vs subscription needs to be presented in a slightly different light. What some fear, legitimately, is that the loss of perpetual is going to happen. What does this really mean? Its the difference between selling a product and selling a service. The user base likes to buy a product, or have the option to do so, not get locked into a service. This is how the subject regarding perpetual options vs subscription only needs to be phrased.
Product vs service.
