There's no spite or emotion, it's a company. They want to kill NewPipe etc. to force everything through apps they control and can monetize. It's just about money.

A company is a group of individuals acting together for a goal that could not individually be achieved, the legal personality of the company exists to reduce (not eliminate) the liability and coherently steer the members of it. Those shareholders/business partners individually wouldn't be able to earn this much money nor have this much work done by employees of each.

Yes, there is. The people who got rich absolutely think they deserve it all.
