The benefit of the doubt... that corps _don't_ write clunky, slow software?

When the supposed to bug happens to conveniently cause issues for adblocker users, yeah.

Possible, but still just an assumption.

Google does - Google search and maps have gotten objectively worse over the past 2 years. At least in Canada.

I have 38 locations in my (huge) city saved in Google maps and it breaks when I ask it to find a way from point A to point B. Works fine when logged out.

Maps also put traffic signals where there are none, and while finding shortest path it stopped putting weights to traffic signals. So you could have it route you via a city's main street instead of the freeway because it's 2km shorter but it ignores the 9 traffic signals that wastes 15 mins. Apple maps works fine.

Google search on web has adopted bad UX, and clicking a map or a shopping item has a noticeable delay between. Also right click "Open in new tab" options are gone.

Are you saying all these "enshittification" changes are deliberate?

Have you told them yet?
