I don't read it as celebrating abuse. clearly there are better ways to correct peoples mistakes. As adults I think we all recognize that. I assumed the upvotes were because Linus is setting the high expectation that we don't see from Paid OS and Paid software. He is defending the philosophy of the next kernel should not destroy all the downstream work people put in. I'm currently working at a place that sells 3rd party software. It is an expensive product and touted as backward compatibility for 40+ years, and their newer versions have taken a F@©k Y0U approach to users. People with decades of files are now getting screwed and the software company turns down regression and bug reports and wants them submitted as feature enhancements. LOL WTF. I wish I could share this letter with their developers and management.
