If you don't want a cyberpunk-like dystopia of megacorps controlling everything, yes. This is not just affecting the VC-funded startups' profitability but it also affects ordinary software developers' lifestyle businesses too. Sure, the core principles of OSS don't require that you'd be able to earn money from your work, but then perhaps it is OSS which is not fit for purpose, not the desire to earn money from creating software.
>if you want to discourage Amazon from using your product, use AGPL.
The AGPL is still not restrictive enough because you can resell the software without contributing anything back if you don't modify it. Stuff like the SSPL or the Commons Clause are much better to prevent that kind of exploitation.
>FL/OSS will be fine between evening/weekend hackers (xz), small-to-medium companies/consultancies (Rails), and our neo-feudal tech overlords (React).
I find the xz example especially funny because that shows how it is very much not fine. Single developer, burnt out, not getting paid a penny for his thankless work, a bunch of state-sponsored actors pressure him to hand his project over -> backdoor injected. If Lasse Collin could get support for his project, this almost certainly would not have happened.
