It would seem, in regards to the topic in question, that Steinberg is at least making a conscious decision. Vendors that chose not to go VST3 made such a decision too, and as is the case here quite a few people complained about that. I am sure they stand by their chosen path, as should Steinberg in my opinion.
VST 2.0/1999, 2.4/2006, 3.0/2008, 3.5/2011
VST 2 SDK maintenance discontinued in 2013
It is now May 2016 and there is plenty of support from vendors in regards of VST3, so Steinberg is not going back. IMHO, any complaints ought to be sent to the vendors that refuse to go VST3 or they never will (maybe they won’t even then), which would mean that eventually you’d be forced to change system in order to actually remain on VST2.
Why do I feel this way? Because I like the VST3 functionality. It rocks, literally!
