Waves is one of the few companies that will refuse to provide support if you don't have WUP. They also only provide one licence for each plugin unless you have WUP.
I love getting random out of the blue updates from the likes of Valhalla, all free and still developed. I'd rather support guys like that and boycott Waves so they change.
Plugin Alliance allow multiple installs, ongoing support and regular sales that are way cheaper than any WUP. They do charge for new versions, but they also make sure the old ones continue to work. The new versions like the others mentioned are generally full of new features. Not like Waves who just want more money for what you already have!
I wonder how many more sales Waves would get if they actually listened/cared about their customers and the market. I'd almost consider this offer just for a couple of the inclusions. But with their current practices, there are better options overall for almost, if not every plugin they make.
Support the Devs that care and listen ?
