Dude... slow down. Take a deep breath.
There's a difference between saying that the best teams play each other at the end of the season, and saying that it is all part of a plot by Adam Silver. Some of it, without question, is just because teams gotta play each other sometime.
Did you take any time to look at the schedules of the ty teams, to see if their games appear to be backloaded? I bet it looks that way. What kind of ratings do you think Sixers vs. Lakers gets?
It's tough to create a schedule for 30 teams, 2,460 games, with conference and division considerations thrown in. Cram it all into a calendar, and there are going to be places where it will look like patterns exist. My point is that, for the most part, I think they have a hard enough times just coming up with something that works. Yeah, they plan some marquee matchups, I'm sure. But too much of that would up the whole thing.
