That's what Steinberg cost a bunch of former loyal customers when they had doubled their typically announced upgrade price into new "x.5" version slices instead of full numbers,
Once again, you don't know what you're talking about! For many years, Steinberg has released yearly upgrades. Every second year they release a full number x.0 upgrade for 99 and every other year they release an X.5 upgrade for 49. These X.5 upgrades are far more substantial than "normal" X.5 updates.
That makes an average update cost of 75,5 for Cubase Pro. Compare that to Arturias upgrade cost to 199-399! Most Steinberg users are pleased with their upgrade pricing model. I don't think that anyone appreciates Arturias greedy model, to Arturias peril.
Once again, get your facts straight (you sound like Trump). Steinberg hasn't raised the upgrade costs. They have
lowered them. And in the process shortened the wait for new versions with new features.
