On the contrary, bay area companies want right wing politics on their platforms (it generates a lot of content and thus a lot of money, after all) but some conservatives tend to break code of conduct rules regarding hate speech and calls to violence, and for whatever reason when they do it makes the news, even though it is a minority of conservatives. There are still going to be lots of conservative people on reddit even if /r/The_Donald gets banned, and there are still tons of conservative people on youtube, facebook, etc. Just because a few highly controversial right wing personalities have been removed from these platforms (usually for hate speech) doesn't mean the platforms are biased against conservatives in general
