I recall some of the discussions, with Sall asking for advice on Reddit's r/GenderCritical. She'd never even really thought about the issue - I suspect that FAQ element was added by some staff member without her being involved, or at least with her applying any more thought to it than "oh, the occasional harmless homosexual transsexual".
She became aware that there was starting to be a problem with males on the app who'd come in as "trans", and was left trying to figure out what to do - women weren't happy with them there, and she was hoping there was some sort of compromise. The advice from r/GC were a bit blunt that no compromise was possible - the males would not countenance being given any sort of restricted access. She didn't quite fully take it on board on the first visit, but a couple of months, in a later r/GC discussion, she clearly had seen for herself how toxic they were and decided that she had to be hard-line, and it had to be strictly female-only.
The Tickle exclusion post-dated that, so when they were explicitly female-only.
This is the CEO of a company that had a clearly-flawed "women only" policy, that saw the problems, asked advice from a radfem Subreddit, and performed a firm reversal.
If you're going to carp at them years later for having ever had a flawed policy, and won't support them now they've fixed it, what incentive would there ever be for anyone to fix a policy?
