That doesn't seem to help your argument: it means that people deplatformed from FB/Twitter should also be deplatformed everywhere else, which doesn't sound like a great policy for freedom of speech or fostering a competitive marketplace.
There was a very real chance that Parler could have attracted a lot of mainstream people. Maybe the 70M people who voted for Trump would have gone there, and started posting baby pictures, which would improve their ratio a lot.

It's entirely possible and reasonable to argue that the current limits on freedom of speech are insufficiently broad, and that the "competitive marketplace" of ideas has very little going for it empirically.
People deplatformed from facebook and twitter were deplatformed for a good reason. So yes, they should be deplatformed everywhere else.
And this policy works just fine with freedom of speech, seeing as hate speech, threats of violence and insurrection are not covered by the 1st amendment, which doesn't even govern these companies anyway.

That's actually a great policy, because FB/Twitter aren't super-eager to ban people for their speech, so the ones they systematically de-platform are usually doing something pretty bad. Note: I'm not saying they always make the right call 100% of the time.
Freedom of speech is not freedom of reach. Society is not obligated to give bad ideas an audience. In fact, it's doing its job if it filters those ideas out.
