Someone understands that drive space is not cheap when you have to buy it. IK's friendly licensing allows me to have it on 4 machines. If I lost a library I get it from another system. I always archive my purchases. I still have quite a few HDDs on a shelf and a drive dock.
I'm a big fan of Kontakt since NI has a compression that makes file sizes smaller.
The trend in all development these days is they have no regard for file size. Look at the size of some phone apps and games.
