Its been obvious the changing of court speeds by all the tournaments to woo the Big 3 for years now.
So yes tennis in its greed has been doing that (and it does make sense as you are always trying to build up tournaments to greater heights.)
I'm not sure how you reset. We are resetting the schedule this year and maybe next. Justice in a sort of way that European tennis is taking over the schedule from the Asian swing with its many Chinese touraments this Fall, but by that time in 2021 we better have a vaccine or we'll have far worse problems to deal with.
Asia will want the tour back.
The backbone of the tour are its tournaments (and biggest players) so you can tinker with the schedule and now is the time to do it, but I don't think an achievable new schedule offers the opportunity for a reset in the terms you wish.
Right now tennis has a very unique opportunity to help lead the sporting community out of this crisis given its unique nature in prevent spread of the pandemic and its ability to handle even a loss of 50% of the players due to pandemic considerations. Golf is the only other popular sport that has this kind of invulnerable nature. Team sports you lose whole teams or enough players and your whole league is toast.
So I think a reset needs to take hold of this opportunity to expand the sport, and expand it with the Big 3 leading the way.
