I disagree, many companies are still great even after going public in the last decade:
Shopify, Cloudflare, Zoom, Spotify, Roblox, and Coinbase are all notable examples.
Of those I only use Spotify and it pesters me at all hours of the day.
"Great" for the majority of these is a stretch. There's no shortage of complaints about how Spotify treats both artists and customers, and Roblox enjoys yearly controversies from how it provides access to and exploits its customer base of children.
I use Zoom and Spotify and both of those have gone downhill dramatically. Spotify to the extend that I really don't use it anymore.
Bruh, Spotify has been absolutely shit, and their practices and push towards AI and completely unusuable suggestions algorithm are making it more and more shit.
I take uber every day and haven't found it to be "enshittified" (outside of some ads appearing in the app now).
It started off enshittified
It's not a big deal but the cars allowed on Uber has worsened. I remember trying to sign up as a driver a few years ago with a 2009 Corolla and being denied because the car was too old and now see cars from then allowed today. Maybe that's the cost of scaling but I find it worse. Also no more Uber pool.
The enshittification is definitely happening on the driver-side with wordened working conditions and pay.
I like Uber but I was surprised at how bad their mapping is - they get the route to get me home wrong and I've gone through the process of telling them about the mistake in their maps and they just seemed to ignore me.
