An investigation from a neutral third party is a good thing, but in this case LTT hired the third party investigator so the investigators obviously have an incentive to find LTT innocent of all charges since LTT is paying them through Linus Media Group (LMG). It’s better than nothing, but it’s like when there’s an internal affairs investigation into police misconduct… by the police… Nobody believes it and for good reason.
I haven’t seen anyone mention it yet, but a reason might be that providing an API is cheaper than web scraping.
If people really want access to your data, they can just scrape your website, but that requires loading all the data through the website itself which requires loading millions or billions of video thumbnails, comments, descriptions, recommendations, etc. It’s much cheaper for them to send a JSON through an API, even though they might know that some people are trying to undermine them by using that data to circumvent their advertising.
