I think I agree with Schumacher. Making tyres that are intentionally bad is just weird. And honestly, more pitstops doesn't mean better races. I'd rather give them good tyres and let the racing happen in the track. If that's boring, then change rules to fix the racing, not to add artificial pitstops.
Also, these tyres are so unpredictable it isn't even funny. They hit the cliff at some point, but then they doesn't, then someone complains about degradation after 5 laps, then someone does 20 laps on softs. I guess that's the worst part for the drivers and the team, it's like tyre russian roulette.
