it seems like some kind of data breach happens every other week.

Yep.

Nobody ever does anything about it besides issue a generic corporate non-apology that was written by their legal team.

Ironically, the lawyer hours to write the non-apology are pretty expensive, right from the start. Beyond that, IBM thinks the average breach costs the company 4.4 million dollars.

Companies tend to get serious about breach prevention after a breach.

But the same leadership who couldn't retain Cybersecurity experts on staff before the breach doesn't magically become good at hiring Cybersecurity experts after the breach.

So I suspect that most pay too much money for too little talent for their needs, and remain at high risk of another breach.

I have no doubt that several sketchy companies know more about my online activities than I’d ever want them to.

Oh yeah. Very much so.

To end this on a more positive note, the biggest single improvement a person can make right now, in my somewhat random, but informed, opinion, is to switch to the Firefox browser.

I could probably be convinced that installing uBlock origin or installing a PiHole are stronger, in a friendly argument over a round of drinks.

Of course, all three of those are compatible, for the truly paranoid.
