That's so confusing lol I was just thinking about Opera after reading this earlier and having some youtube videos on where people keep telling me I need to use it. Again makes me wonder, why is people using a browser so important to these companies when they distribute it for free? I mean, the answer is clearly, at least my assumption is, they're stealing data and they all want that sweet sweet data. But, what is the user supposed to feel is the reason? I feel like the only reasonable explanation is that they're trying to rope more product in to sell data but they don't even seem to be trying to hide it. I just feel like I can't think of an alternative reason any company would care if we used their specific browser.
