I'm not sure if the Jetbrains model backfired with the Ukraine war, considering most of the dev team was Russian and they decided to close the Russian offices.
I remember that the launch of the 2022 versions had a drop in quality, I don't remember when was the last time I had crashes in a Jetbrains product, but with the launch of 2022 versions crashes occurred on a daily basis to the point I really considered cancelling my subscription, and I activated for the first time the option to block updates in Jetbrains Toolbox.
Months later they launched their promotion to keep the current pricing for 3 more years and I renewed. I acknowledge that promotion was a genius move by them, but I'm unsure if that promotion was a result of a drop in income for them.
