But solidarity - amongst the left - if taken seriously surely means it's the left's duty, responsibility to remove corporate services from their lives as much as possible. Soliditary sometimes means to boycott services, and it sometimes means you might have to make things a little bit more difficult for yourself - i.e. take a less easy option.
The #Fediverse is in many ways that kind of solidarity, with people being here, hosting, developing as part of a solidarity project.
Well said!
