Open source is about sharing and forking, not collaboration.

Collaboration is a common pattern in larger projects but is uncommon in general

A PR, at best, is collaboration, not a transaction.

If you read the post till the end, I am open for lots of forms of collaboration. Its just sending chunks of code diffs around is becoming increasingly like sending diffs to resulting binaries. Just inefficient.

I'll take that source every time, even if you do not want my contributions.

Nowadays with genAI my powers to solve bugs and add features have unhyperbolically 100x'ed.
