I'm not sure why you're being downvoted, you're right. Using software that has requires people to contribute back is a huge liability, and hurts adoption, which is the most important metric for herdr right now.
Seems like the path is to use LLMs to launder code from VC funded efforts and their public codebases into codebases with a copyleft license. Otherwise you have to wait for the rug pull before taking action (Terraform and Vault->OpenTofu and OpenBao). It is fair use to train and create derivative works after all, as courts have ruled so far.
They're right, but they're presenting it in a way as if the toxicity of AGPL is the actual truth, and not just the opinion of greedy corporations.
Being toxic to greedy corporations but beneficial to everyone else is the point of the GPL licenses.
