Non-wealthy inhabitants of San Francisco and Oakland sabotage the municipal bicycle-rental systems, using it as a proxy for the gentrifiers.

Bicycle rentals are not "sharing", so "bicycle sharing" is a misleading PR term. Please let's avoid it.

Bicycle rental systems as such are not bad, but these systems are unjust and intolerable because they track their users. I would not propose to eliminate them, though; better to fix them not to surveil (see https://gnu.org/philosophy/surveillance-vs-democracy.html).

The non-wealthy residents have discovered that sabotaging bicycle-rental is a way to fight gentrification. Urging them to think instead of it as merely a transportation service is valid in a shallow sense, but totally misses the point. First, those people surely know whether it will serve them or not. Second, if you want them to stop defending their housing this way, what other way do you suggest?
