Fascinating thread! I only read the first and last pages, plus a couple in the middle, but I honestly believed the original post was basically just a plug for BFD disguised as a complaint. Then people took it seriously and we got 8 pages. :)
I bought into the Superior Drummer ecosystem some years ago, and so I am sometimes amused when I see the array of drum VSTis I have available now: Superior Drummer 2, Superior Drummer 1, Session Drummer 3, Addictive Drums 2, Stormdrum 2, Studio Drummer (from Komplete) and Battery (also from Komplete). Beyond that there are extra samples from the Drum Replacer, plus probably a few kits buried in Dimension Pro, old-school 808 and 909 samples in one of the various bundled VSTis, etc. And to think that 15 years ago I had to scavenge a handful of samples from downloads and magazine cover CDs just to get anything sounding remotely drum-like. :)
So, yeah, I don't
need all these bundled drums. Maybe some even get in the way, given how bloated my plugin menu is. But I seriously doubt Cakewalk have to invest much time, effort, or money in pushing these plugins with Sonar. The plugin manufacturers make their money primarily from upgrades and selling add-on packs, so it's unlikely much, if any, of the Sonar price goes towards paying for such a plugin. It could even be the other way around, with XLN Audio basically paying to get their product in front of Sonar customers. (Hard to know, without being aware of the relative market share of each DAW and drum synth.)
It's perfectly fair for people to say "the thing Cakewalk are adding... is something I don't need". That's a data point that can be taken into account. But I don't think the price has changed because of this, nor has any other feature suffered.
