sounds like no one has forced you to do anything, sounds like you made a choice. Whether it is ok for them to have criteria around employment based on vaccines is a valid concern, especially for a remote worker, but this isn't about being forced, this is about whether it is ok for them to choose whether to employ/do business with you based on your choices around vaccines. I think if there is any reasonable expectation you'd interact with other people, their clients or other employees, even if irregular, then yeah, it would be reasonable. But if you are 100% remote, with no expectation of interaction with anyone, then it doesn't sound reasonable.
