Not sure if Qt6 has anything to do with the original post, but Qt subscription model is inherently flawed. JetBrains, since the article mentions them, offer subscriptions, but with each payment, you get a perpetual license until that point in time, so if you stop paying - you only stop getting updates. When JetBrains tried to switch to the subscription model, there were similar problems with their clients, before coming up with that solution, so I hope Qt get sensible and don't do that or they would lose more than they would gain.
