I'll add another perspective to this: I think you can divide the answers to that question into 2 categories:

1. The self-hosted vs. cloud-hosted solutions
2. The open-source vs. closed-source solutions

In general, when people think about Linux, homelabs etc., most people naturally tend to have a bias towards self-hosted and open-source solutions - which I understand perfectly well.

For this particular question, I also believe it has the effect that any answer, that mentions and links to a self-hosted and/or open-source solution, is automatically more accepted and taken in good faith, than any answer pointing to a cloud-hosted and/or closed-source solution. Again, I completely understand and agree with that.

So naturally, open-source people would probably rate the reliability of answers like this:

1. Self-hosted and open-source
2. Cloud-hosted and open-source
3. Self-hosted and closed-source
4. Cloud-hosted and closed-source

As far as I can see, the answer by Vlad falls into the third category (first I thought it was cloud-hosted, but it is actually something you have to install yourself).

But when you add to that all the red flags that Nmath mentions, it's clear to see why it comes down the priority list, and also smells more like spam/scam/slam than a serious answer.
