Not all dealerships remove their brandings/emblems/logos themselves. I purchased a $42k Ram truck recently and I had to spend some time removing their license plate frames and, using a heat gun and a lot of patience, removed their glued on emblem from the tailgate.
For me, the two are the same. Whether I am buying a $600 phone or a $42k truck.. I am buying it. Period. By definition that makes it mine (and the bank's in the case of the Ram, lol). I am not paying bookoo bucks to flaunt their logos around for them. As mentioned, I have removed the dealer's stuff from my truck, and I have been considering removing certain Ram badges as well (referred to as de-badging, for those who are unaware) since the 'Ram 1500' on both front doors take up nearly 70% of the real estate on the doors. I'm not a Nascar driver, I don't plaster my truck with brand stickers or emblems. Now, if those companies decided to donate parts/items to me for use on my truck, then I would probably reconsider it. (I certainly wouldn't turn down a S&B CAI if one were offered to me!) But until then.. no stickers.
Same goes for my VZW phone. The sticker logo is admittedly tiny in comparison to other VZW phones I have had in the past. And, bonus, it is removable. If I wasn't so taken by the appearance of the ballistic nylon backing, I would have simply slapped another Seidio case on it and called it done. However, I am one who is loving the clear case idea in order to put the appealing BN on display. Therefore, the VZW logo - at least on this phone - had to go.
Bottom line: If I want to parade around displaying logos, I'll buy a $30 hoodie sweatshirt with 'Salt Lake City' or 'Ram Trucks' or -insert brand name here- on the front and call it a day. Or I'll pay out $12 for a clear/naked phone case with 'PureGear' plastered on the back. I do not care to pay out hundreds, or thousands, of dollars for most anything that forces me to be a walking, talking billboard when I do not want to be one. I prefer the option.
