The trick is, if you have a particularly strong or unique brand, you can count on being the number one organic result. HOWEVER, if competitors bid on your brand and you do not, they end up above your brand in results as part of the the paid/promoted position.
This usually forces brands into competing in paid positions on branded keywords that they should "win" naturally. Google rationalizes this by charging more relevant results a lower rate, but it still doesn't excuse the fact that the brand shouldn't have had to pay in the first place.
Best part of course is that Google has been constantly making it less clear whether something is an ad, so the tricking is really primarily done by Google themselves. The advertising is really just paying to be the first search result.
> Google has been sued frequently for trademark infringement because it allows advertisers to purchase trademarked names for use in AdWords by competitors.
> Google has never lost one of these cases.
> Google derives 97% of its revenue from advertising, annual revenue that was over $109 billion as of 2017.
> These conflicts illustrate a serious problem with how internet advertising is conducted.
Perhaps they settled every single case. Show us one that went to trial.
