I don't think they realise the damage this change has done. I have been on board with or ambivalent about most of the changes. I don't care if there's less moderation, I think Twitter probably did have too many employees, and I like the idea of a paid account with fewer (preferably no) ads. I'd even have happily paid Twitter to continue using Tweetbot. But this has destroyed the trust and the user experience of many…
I had thought since they first started locking down 3rd party apps years ago that if/when they ever had a "Twitter Pro" or whatever, that allowing subscribed users to use a third party app would be part of it. After all, lots of online service subs eliminate ads in the product, so why not Twitter?
I assumed rational thinking on their part, I suppose.
