So is this so-called loyalty that is not absolute is absolutely no loyalty? Joke aside, I don't believe such rage is necessary. Do you still like the writing of WaPo? If you do, why not just continue the subscription? Heck, I still read WaPo even though I believe they are too biased towards the left and sometimes become hysterical and dishonest, as I still value their perspectives.
It leaves you wondering what other WaPo coverage is being edited by Bezos. Erodes trust in the publication.
You can agree or disagree with the endorsement they were going to make, but the fact that the owner blocked them from making it means that they lack journalistic independence.
Traditionally, quality broadsheets, even where owned by a person or company rather than a trust (the latter model is often preferred) have editorial independence. “Owner controls editorial policy” is more of a tabloid thing, so consumers looking for a quality broadsheet will likely go elsewhere.
