What's the alternative, users wait for some porting house to finally get around to releasing an update to be compatible? Oh, you don't have it in your contract to do that work, and the parent company isn't keen to pay you to do it, sorry users. Maybe your update is now a paid update, so people can either pony up, or not upgrade, or abandon your software. Hello CS6. Was your latest update $10k? *major enterprise developer thanks you for the multi million dollar windfall your OS update gave them by forcing all their deploys to pay for a compatibility update, caused by "you". Being a major platform developer is full of hard decisions balancing user experience and security, performance and future looking direction. It's not a problem most developers have to concern themselves with in your average app.
