Whenever google bites the dust, it's going to seriously fuck up the web engineering and online advertising space. It's basically google driving much of that ecosystem and BILLIONS in advertising spending every year.
I don't think it's a bad thing for that to happen, but I also kind of think it already would have happened if we had any sort of decent data privacy laws in the US. Google's (and FB/Meta's) entire business strategy has been unravelling since the EU started enforcing GDPR, and we are seeing the subjective quality of ads and services dropping because the platform providers can't do (as effectively) what they were doing before in terms of microtargeting.
And while I 100% agree that you're usually better off rolling your own version of a thing.... Bruh. Most people can't even work a damn Chromecast, much less set up and maintain an in-home server. Even with that Umbrel product (which does look really nice, gonna have to look into one of those....) it's still on the end user to actually install, configure, and administer those application on their box. Hell if it were between buying a family member one of those, or just paying for a google photos subscription for literally the rest of their life, I would go with the subscription lol.
Fuck being family tech support
edit: it does seem like the Umbrel is pretty overpriced for what you get though, I found similarly specced boxes on Amazon and AliExpress for like $200
