I’ve always personally disliked MIRC as a product, mostly from a UI standpoint. I feel there were also some bad choices around its scripting support, which in the early days, put casual users at risk of malicious actors. However, I think KMB made the lifetime agreement in good faith as a (mostly?) solo developer. I don’t see a huge amount of growth in Windows IRC usage, so this would otherwise likely be abandoned or largely unmaintained. If someone is big on him keeping his word and he sends the key, I don’t see a huge problem. The main concern I would have is in the extremely unlikely situation there was a ‘important’ deployment of mIRC that suddenly stopped working without warning, but that would have been three years ago.
