Why do some exchanges bomb your mail box with suggestions on leverage trading, futures trading etc and still not be held accountable for financial advice

A recent email from MEXC reads: If you're just getting started with trading futures, we recommend practicing with a MEXC demo account to build confidence and improve your trading strategies without risking actual capital. I was then thinking that in my crypto journey l've got hundreds of such mails from different exchanges, offering services that, at their very core, are gambling. We all know how dangerous e.g. leveraging is in such a volatile market, and yet these companies keep pushing us to do so. At the same time, their Terms of Service state that we should not take any of their proposals or messages as financial advice. It's like "wanna buy? OK, none of what we offer is financial advice, but since you're here, here's a 125x leverage for you!" This is predatory specially for newcomers. We've seen lots of people getting rekt in this bear due to leveraging, so please avoid it. Even though exchanges are advising/luring you to do so, they can't be held accountable in case you lost it all.
