A couple of things here, this is of course a pressure donation where people don’t get the time to think about who they are giving to.

If a company does it right it should have information about the charity readily available. If not, this is a shitty practice in my book.

Many nonprofits have a high overhead. If this is the case a big percentage of your donation could be going into the pockets of administrators.

Also, while the company doesn’t get direct benefits, it does get indirect. Like a goodwill vampire the company is leeching on the act of giving.

Lastly, while the company doesn’t directly financial benefit there are no rules saying they can’t promote a charity that their employees/owners/shareholders have involvement in.

While this may not be a bad thing there is nothing preventing them from picking a charity a major share holder runs thus enriching them especially if the nonprofit has high administrative costs.
