What do you mean by less power? It's different.

One manufacturer can't force you to buy stuff you don't want, nor ban you from buying from a different manufacturer that does what you want.

(In contrast with the FCC, which has a lot of power over you, by banning you from buying what you want.)

Why would one want specifically to buy a product not conforming to the choice described in the first-level comment?

If it's useful enough, and the existing manufacturers leave significant customer needs unfilled, competing suppliers can step in.

All kinds of reasons. It might be cheaper, for example.
