Conservatives need to build their own platforms.
That would be the logical route to take - under normal circumstances. But we are not living in what could be called normal circumstances. Stop, look & listen - the techno tyrants aren't gonna allow alternatives. Efforts would be made to co-opt from the inside - how could employees be screened to not be adversarial. The IT profession is awash in socialist millennials. Could a company even get away with attempting such screening these days - doubt so. Someone would leak such an effort, and a derogatory pile-on by the left would ensue, which would feed into a coordinated effort to damage the brand. Efforts would be made to buy out alternative platforms, to be another cog in the Google/Facebook machine or subsequently dissolved after acquisition, removing the threat. Lawfare could be employed, suits filed claiming IP violations - that their platform was copied, code "stolen" or some such, tied up in legal actions in friendly courts until the end of time, destroying any fledgling company with legal fees if they were to try to contest the allegations. We're not in Kansas anymore, Toto.
They have declared and demonstrated their agendas and intent, time and time again. It's
war, and they are conducting themselves as such.
