It is that deal from 2006(?) or so. Agreeing to not be sued for an exchange of money is dodgy. Add the competition which was not offered the same deal; add in the environment which was drastically different; it was a shit thing to do. Purely a business decision. I understand why the shareholders wanted that, but that doesn’t make it right nor desirable for me.
Granted, nothing came out of it in the end and Linux managed to get itself established in a way where one could argue is close to impossible to get rid of it, but I feel like this deal is similar to getting stabbed - the one being stabbed will always bear a scar and remember, while others will forget over time. People growing up after this deal will never have experienced the mood and environment of that time which only makes it more difficult to understand why it was a big deal.
