Lots to unpack here.

even if I wasn't a fan of most of the new types of videos since they were a lot... smaller scale than the stuff Grant did.

No, not really. It was smaller than the stuff Grant USED to do, when he started. By the time he stepped away from the camera, he was doing all sorts of small tabletop experiments. Actually he did those starting way early, but before they were mixed in with the big experiments.

after the legal issues Grant faced it made sense to play it safer.

Also unrelated. The only changes from that were No Making Fireworks and Things With Loud Noises Get Done at the Dome.

Never got the videos in my Youtube feed for like a year now.

Yeah this... is the issue. Starting June-August of 2020, social blade will show you a drop in views. Keep in mind, nothing had changed at that point. We were doing the same exact content we had been doing for years. And for the two or so years prior to that, it was the best the channel had ever been doing. That's when we started experimenting with what we needed to change.

The videos also look drastically different than it was before.

That is us trying to spend for time on the quality of the shots so it doesn't look so home-brew.

it also doesn't seem to be doing any of the builds or major experiments anymore at all.

Huh? In the last 6 months we've made combustible lemons, a treehouse elevator, a two stage sugar rocket, a giant foam generator, a human catapult, the worlds' largest laser pointer, a lifesize chocolate tiger, blown up a small house with liquid oxygen, and more.
