I was planning to buy several Insync licenses for use on Fedora on the next big sale which is… now. But from all the threads about bugs and the subpar support (lot’s of threats without any reaction or problem which get fixed and later resurface again and again) I’m not so sure if that is a wise decision.
I’ve installed Insync on FC31 with a Google Apps Testuser and one (!) .doc file and have a constant CPU utilization of 20-30% for insync and QtWebEngineProcess
One of the accounts I wanted to use with Insync has several TB of files in it and I don’t feel like playing Russian Roulette with them. So, for now, I guess I can and sadly will “vote with my money” like @jbr put it.
