To Photoshop; perchance, to Google
“The Photoshop trademark must never be used as a common verb or as a noun. The Photoshop trademark should always be capitalized and should never be used in possessive form, or as a slang term.” What’re these people thinking?
Chill out, Pops. It’s a matter of trademark genericization. You can’t verb a trademark proper noun… but a common noun, a part of speech, why those get verbed ever’ day. And parts of speech, why, they are not trademarks. They are English.
Just Google a little to find out what I mean.
