Any electric gear with the battery as its main wear part. Ebikes. Sit-on mowers. Cars.

This is about so much more than cost. Agency, autonomy, environment, efficiency, geopolitics even.

I refuse to buy drm'ed gear. The exception is second hand where I can reliably avoid the drm with little effort. At its simplest, that means never using specific drm'ed functionality. At its most complicated, that means mitm'ing an encrypted can bus.
