"for a better experience"
Do people writing this type of copy actually believe this?
They don't specify who gets the "better experience" (hint: it is them, harvesting the ad dollars)
No, they do not. They just value their silicon valley paycheck over personal integrity.
And really, this isn't a big deal. It's a bold lie everyone can see through, but it's not nearly as consequential as other bold lies society tolerates or is complicit in. Many of these lies make modern society function in the first place - they're necessary fictions everyone participates in.
This lie is... laughably irrelevant, which is why calling it out won't make you a pariah. People are jumping at the chance to point and laugh when doing so carries no consequence.
Other examples of inconsequential bullshit: "Your call is very important to us", "We value your privacy", "We're like family here", and "It's not about the money".
tl;dr: "whatever."
you'd be amazed what you can believe when eating food and sleeping indoors depends on that belief
