Twitter, Tumblr, Facebook, YouTube, Reddit, etc., for better or worse really don’t represent a left or right ideology. They represent the mainstream. Now, you or I may find that mainstream too conservative or too progressive, but I do not believe that any of those platforms are ideologically driven one way or another (even Tumblr, where the userbase is historically younger and thus more leftist, banned porn (a distinctly anti-leftist move) and has historically had a much more laissez faire attitude towards banning users than many left-leaning people would like…). It’s important not to confuse the userbase that is most visible on a platform for the platform itself).
The Freedom Phone isn’t targeting run of the mill conservatives. Those users are just fine using their iPhone or Samsung. It’s targeting people who are zealots and convinced the world is against them. It’s targeting Q Anon believers (tho not exclusively) and people who think Fox News is too left of center. That’s why it’s a grift. It is targeting people who would rather adopt something that is a scam, just because it agrees with their idea that the system is rigged and everyone is against them.
As chipotle_coyote says, there are, for whatever reason, less scams aimed at leftists. I don’t think it’s b/c the group on the right is any less intelligent, but because the nature of this sort of culture tends to be that the left eats its own, so selling a specific grift to them is a lot harder.
As for whether Twitter, Tumblr and friends are canted to the left, here's why I'm doubtful of that. (Also doubtful of the inverse, to be clear.) It's fairly trivial to create a Twitter, Facebook, Tumblr, etc., follow list which is curated to your favored sociopolitical bubbles -- that's basically going to happen if you use the sites as designed. The more you interact with those bubbles (e.g., what you like and what you retweet/reblog), the more focused they become.
Okay, so, that's all probably pretty obvious, but here's the thing. Once you're in your favorite bubbles, the problems you see on, say, Twitter are going to be the problems that bubble experiences. If most of the people you follow are deeply invested, either directly or indirectly, with far right activism, you're going to see and hear about far right activists that Twitter has flagged or suspended or banned. If most of the people you follow are deeply invested, either directly or indirectly, with LGBTQ activism, you're going to see and hear about LGBTQ activists that Twitter has flagged or suspended or banned. But those two streams are very, very rarely going to cross. And that makes it very easy to think it's your particular in-group that's bearing the brunt of Twitter's evil machinations.
No capitalist would steal the surplus labor value of the workers involved in making the phone.
It would be hard to get the entire supply chain to fit this model without first creating an organization like Mondragon. [1]
