Because I agree, the forced obsession with "growth" at all costs, which seems necessary to operate a public company (at least in this century[1]), is imho the #1 reason why enshittification is unavoidable.
[1] I'd describe nearly all present-day corporations as fixated on quarterly results even at the expense of business viability. Something I truly don't understand is why big companies say, 75 years ago seem to have been so much less that way. If anyone has any theories I'd love to hear them.
Just running Google as-is without ads would have produced less value in the long run. Plus the SEO tide (which relied on DoubleClick ads that weren't yet owned by Google) began to rise and would've drowned Google Search much earlier if they hadn't grown.
Where I think Google took the bad (for consumers) turn was when they purchased DoubleClick and began to consolidate the entire ad business. Instead of losing money to SEO spammers, they began to make money. This put Google into a conflict of interest against their own users. Ever since then they've been piling onto that conflict of interest, draining more and more value from their products.
People overwhelmingly prefer ad-supported to subscription supported. Google would be a dramatically better service if everyone who used it paid. I really, really, cannot overstate that.
The internet sucks because users feel entitled to everything on it for free. They don't want ads and they don't want to pay subscriptions. uBlock origin, archive.is, and constant complaining about how the content sucks.
The internet is full of children with a naive understanding of how things work. The are so deluded that they even call on companies to simply provide them everything for free if they want to be "successful".
The notion that Internet sucks because megacorps have to scrounge for cash doesn't pass the most basic smell test.
