Fear of abuse is just the excuse entities use to avoid providing services they have other reasons to oppose. Heavily abused services continue to exist if they're profitable enough or sufficiently socially useful.

All adtech and most social media is both abusive and socially destructive, but it's profitable enough for the Right people that there's no serious prospect of it being shut down.

The road network sees a lot of abuse (e.g. transportation of illegal property, impaired driving, simply allowing criminals to move freely) but it's too socially useful to shut down.

Fear of abuse is just a cover for withdrawing, or failing to provide, services for other, unstated, reasons.
