Yeah if they made it so that you had to pay $5 per month or moderate a sub with >10k subscribers to keep using third party apps, none of this would happened and they would have been able to make more money off of it.
$5 a month is still a lot imo. i'd do $12 a year ($1 a month billed annually or 6 monthly) which is still an order of magnitude larger than the amount they would get from advertising for me
Yeah $5 is a bit much for what it is. I picked that number because it's the upper limit for where I'll go "fine have money just don't bother me any more"
