I wouldn't be so sure, a big part of growing big as an organization is becoming extremely sensitive to the political winds, and Youtube's "content moderation" is really a function of politics in the West. Were Rumble to grow to a comparable size it too would face the same political risks and at that point it could only remain as it is if there was a sizable political force backing.

Someone already mentioned Odyssey and I too am more hopeful of that platform - a decentralized platform is the best positioned to avoid political interference and censorship.
