I mean as a consumer I see it as a mark of disrespect from the manufacturer to plaster its logo everywhere. I am paying for the product, not to be an advertising billboard ffs! If you want me to advertise your product, let me negociate the terms and my retribution. This was particularly annoying on road bicycles in the early 2000's where most bike manufacturers would put as many are 7 or 8 logos on the frame and every single component maker would also do the same with loud bright on black logos for every single other part.
see this example of a cannodale supersix of that era: https://files.bikeindex.org/uploads/Pu/582923/large_BRD28952...
Bottom line: when I am restoring a bicycle, motorbike, whatever, the first thing to go are usually the branding and logos.
Most things are ugly though. The stuff people restore (like classic motorcycles) often have pretty great aesthetics and that's part of why they want to restore the object.
