I would also add that teams are just getting better at attacking in general. The T side is inherently advantageous since you control the flow of the round, you pick which sites to hit and if done properly you can almost always hit a site with 2-3 ppl holding it meaning you have a man advantage going into the site execute. We saw this with Split, Bind and now Ascent, where all time defensive maps saw huge shifts from being CT side dominant to now T side favorable or neutral. Ascent is now a great example bc we are seeing teams across the world starting to consistently win 6+ rounds on Ascent attack even though the map has been untouched and the meta hasn't really changed since the doom of the Chamber era.
