I think the word doesn't have a good analogue, so I support it. I wish it sounded a bit less sophomoric, but the concept is sound, because it's the intentional worsening of a product to extract more revenue, not just by charging more, but by being worse for the intended purpose.
I don't think degradation or decay capture this...those are more associated with a process in nature, or due to the laws of physics, but especially something unintentional (like "bit rot").
I like Cory Doctorow, so I might be a bit biased here. Would be interested in alternatives that capture the intentional aspect.
I don't know, I like that it somehow implies it is caused by humans. Decay is a natural process, sometimes unavoidable. Degredation is often used in the same sense. But human and organisational decisions are driving this.
The enshitificstion begins.

If something is valuable to you, paying for it to not have ads is very reasonable.
