There's definitely a personal choice element here. Some of us like to wear what we play proudly, and others couldn't care less...
I've had endorsements (I've allowed to lapse). Recently, when playing on a TV show, backline supplied Yamaha gear for me (not uncommon). I really didn't feel like giving Yamaha the free advertising, plus I'd forgot to bring the removable band logo, and I had the logo covered up. It's doubtful anybody even noticed, and it satisfied my desire not to advertise.
fwiw, on my gear rider, I don't specify any one drum co. anymore, just examples of what I deem acceptable.
in addition to amplifiers and some keyboard brands, Bass-reso head logos are just a wee bit too big for my taste. Drums don't really have an iconic, brand or style identifying shape that helps the viewer to identify if not the brand, then the 'style'. i.e. Fender Strat or Tele body. Gibson Les Paul; even less widely known brands have some visual identity, i.e. Godin Guitars, Chapman Stick, Steinberger, even Takamine/Ovation guitars. Drum Lugs do serve this purpose, except that their size makes them more difficult to decipher when viewed on stage or on TV (Big screen tv's aren't fair...)
