I mean, that's the entire point, yes. Some financial transactions, at some level of scale, should not be private.
For instance, if you abolish KYC, you've just fully legalized all insider trading. Perhaps you can see that there are some conflicts of interest there. On the crypto side, KYC allows the IRS to go after traders for capital gains tax. Without it, crypto would be an easy way for the ultra-wealthy to just completely bypass taxes, since you couldn't prove that it belonged to them.
I know corporate America doesn't really deserve any meaningful amount of good faith, but for whatever truth is worth, "sustainable" in a business context has essentially always meant financials. A platform like Twitch is generally going to have really high operational costs between infrastructure, network traffic, engineers, and revenue sharing with streamers, and given that Amazon doesn't operate Twitch for charity any more than you do your job for free, they need to make sure that they actually have sufficient revenue to be able to make the finances sustainable. I won't pretend to know how profitable it is, if it even is yet, but cutting employees is obviously a pretty easy lever to pull to reduce costs if your operations can get away with it.
