But removing old drivers from the directory of your FTP site, making old datasheets unavailable, threatening to sue whoever attempts to post a mirror of the drivers site, it's a different matter. Keeping these things available woudln't cost much.

I worked once for a company where half the calls to customar support was for ancient products. The cost of responding to these calls with "we do not support this fossil" which usually took several minutes because, invariably, "can you just answer this" or worse came up was enormous. Maybe the removal of the above is the only way to get rid of that cost.

Anyhow I see nothing wrong morally or otherwise to do whatever you want with something you own.

If the above action bt a company offend you, stop dealing with the company and - if you need to vent - post in a forum why you did so.

Caveat emptor
