> companies like Amazon abuse FOSS licenses to stand up their own hosted versions of open source projects
This is not an abuse of FOSS licenses. If developers have a problem with this, there are open source licenses that would make this use case less attractive for Amazon, like the AGPL.
That licence tends to have the dual effect of dissuading otherwise valid users from using it, because a lot of devs and corps see “something something GPL” and just shut down.
