It is, yes. They do a ton of really small updates all the fucking time now, sometimes breaking critical shit, sometimes fixing things. (I don't remember which version it was that ended support for PANTONE; now you have to pay for a subscription to PANTONE also, and the plug-in is trash and buggy as hell.) Since it wants to be always connected to the internet now, it's more of a pain in the ass to pirate, although it's likely still possible.

I have to use it for my job, so my company pays for it. But TBH, if you're an industry professional, there's really not any viable options on the market. Half the stuff clients send to me are in proprietary formats.
