I feel like you're somewhat viewing this from the wrong direction. Let me paraphrase to make a point.
I went into my supermarket yesterday. They have thousands of different products on the shelves. Worse, the products run out and I'm expected to come back next month and buy more. Is this sustainable? Do I have to buy one of everything every month?
If you're drowning in new SaaS products then you're spending too much time looking at them. You're not expected to know most of them exist, much less subscribe.
SaaS is no different to anything else. They are businesses selling products to customers. If you're drowning in those wait till I tell you how many shops want to sell you bread... (or how many species of bread there are.)
