I have absolutely no problem with them changing the rules and regs between seasons. I find seeing which team/driver rises to the new challenge to be a fascinating part of F!. But it does rather annoy me when they change the rules within a season. That always feels like interference and moving the goalposts...
Even though I'm more interested in the technology than the rivalries, some of the changes have seemed unsportsmanlike, and I don't care for that. I'm definitely in the minority, but I think the change to hybrid engines and the revival of turbos is cool. Screaming V-12's are thrilling, but it's one of the few changes that have allowed them to advance technology other than aerodynamics, and hearing the tires slip is interesting.
