In my decades of press release writing, I've found that it's optimistic to expect to find product or company names spelled consistently on the owner's website.
Sometimes, this is a good thing. It's good to have spelling variations on your site, so people who type the variants that are lesser-known and less correct will find you in Google. But there's something to be said about knowing how to spell your own product name, too.
If you think it would be good to include misspellings of your company or product names on your website, then place these incorrect versions of your names in your images' alt tags. Or find other places where your prospects won't find these errors.
