Was there really an outcry?
I actually only ever really noticed 'feedback'. OK, perhaps some of it was a bit more 'aggressive', but unfortunately you always get that; I thought it was very much the minority of the feedback, though (although I don't claim to be intimately familiar with all postings!)
I'm a bit ticked at how it worked out. I did pay for v12, and I reported a number of problems, some were fixed and others are being worked on, and some will not be fixed and/or changed. If I was part of the problem with the public beta, I do wish they would tell me, just as FYI.
However, it's not a big deal, and I'm sure the development staff is struggling with how to provide public access to the beta without creating (real or imagined) obligations that the beta always work perfectly. So they tried total access and it must have become more trouble than they gained. They try new features and keep some and get rid of some, and I just figured that the access is also in "beta", easy come, easy go...
By blocking access after being public, they have quieted whatever they needed quieted, and they have also lost a number of good meaning users, life is full of trade-offs.
In the end, when I paid for v12 there was no contract, no stated access and this is their program and their company. I'll get v12 when they are done.
I know at my company, there is no way in hell, we would ever do a public beta, ever.
At this time, I see no point in checking this forum very often or reporting any bugs or issues with the public v12, since I have no idea if it's already fixed.
