The point here is to give people true information to make an educated buying decision. People can look back and see that you used Ernie Ball strings when it wasn't part of a contract. And now that you have a contract with Ernie Ball, they can make an educated decision whether they believe that you're still using the product because you like it or whether you are just using it now because you are paid to.
This creates an incentive for companies to create a good product that people will promote on their own, rather than creating a bad product and paying people to promote it.
The Swedish tax authority has several documents on how they judge such cases, and in general, a company doing this is unlikely to be seen as a "no strings attached" gift. If it comes from an advertisement budget, someone somewhere is expecting a return on investment.
The league - his employer - reminded him of the conditions of his employment. There was nothing preventing him from wearing Adidas from HEAD TO TOE as long as it wasn't in a direct situation sponsored by his employer. Thus, he actually had TWO sponsorships in some terms.
He wanted to wear his Adidas on the field, but was not allowed, even though it was completely above the board. So, where do you draw the line? Can your employer tell you what brand of clothing to wear? If he got the shoes for free, should RGIII be allowed to undermine the other contract?
My perspective is that the line of reasoning you present is inherently flawed. Are you not aware that Nike essentially got its foothold (pun intended) by giving away shoes to college basketball programs and people who probably couldn't afford to buy them? It was covered in an ESPN 30 for 30 so there's the citation.
From your context it sounds like you believe - maybe it's my interpretation - that things given to celebrities for free are "no strings attached" and I think that's been proven wrong time and again. Contracts, handshake deals, they don't work that way. There's either an explicit (preferred) or implied (bad) debt to be paid. It takes time to learn how these systems work, and woe to those who might minimize their practical implementations.
Oh, and a Youtuber who receives free stuff better disclose it, because if they're in the US, then they have the IRS to deal with. The IRS doesn't screw around with compensation. Dollars or donuts, keep the receipts[1]!
[1] Excluding Mitch Hedberg, who accurately pointed out a donut in regular guy life does not need a receipt.
I don't really see any ambiguity here. Just ask, "Would I want to know about this if the celebrity's actions were a factor in my purchase?"
The second scenario is one that again I'd draw the line at my own accounts. If I like the brand and they give them to me for free, then I'll disclose it because, well, it's a sponsorship by them. The "would've bought it anyway" kind of feels like a rationalization to me. A lot of things I like I can't afford, so posturing it as such wouldn't be honest in my book.
I think an analogy might be like how NASCAR drivers have a ton of sponsor patches on their racing uniforms.
So, Jeff Gordon for instance - if he makes an IG post where he's changing the oil in his personal car, not wearing his racing outfit, but acting like "Just a normal dude like you!" and prominently holding a quart of Valvoline, I think that should get a tag because it's a grey area. Not everybody knows his race team and his career is sponsored by Valvoline, but if he shows that his sponsorship extends to his "personal life" then yeah, put the tag on there.
I'll definitely agree that the imperfect system / blurry distinctions take some discussion, but I'm glad to have a chance to hash this kind of logic out.
Having a company rule where staff can't accept free lunches from other companies is surprisingly valuable. 'Free' things are often really expensive.
What if then a new guitar brand asks to you to use their guitars? And they're amazing. You'd use them for free anyway... Etc.
I think the lines are blurry. But I agree - the celebrity promoting the teeth whitening rebill to eager teens probably needs to point out their teeth are white for a different reason.
