Yup, that mouse isn't for me. It's also not for a number of people who end up buying it. That's how reviews work: people who had negative experience talk about it so others like that (you know who you are) will not buy that mouse. We also talk about software/hardware design here. Acknowledging that wider accessibility means designing for people behaving in different ways and it saves you from years of repeated complaints - that's also important.

This isn’t an accessibility issue, this is a “stop putting your head in the sand” issue.

But what you're doing is even worse - complaining to strangers about legitimate complaints of strangers

As evidenced by other responders, no it isn't a legitimate complaint.

Every time it's mentioned people come out of the woodwork to complain about "how can I use it while it's charging".

Meanwhile the people that actually use one know that isn't an issue - and rebut the complaints.
