if there were a real business that actually had hashrate and were mining bitcoin then it would have made a lot of sense to invest in such a business. i have done it in the past (a long time ago) with GHASH.io and it makes sense since the user doesn't have to worry about maintenance, cooling, electricity cost, even legality of mining where they live.
but the problem is that "cloud mining" stopped being legit a very long time ago and from maybe around 2015-2016 every single cloud mining has been a terrible Ponzi scam.
