You're welcome to your opinion.
> 1/ How easy is it to get data in? Seems standard.
It supports a MySQL adapter and a PostgreSQL adapter and then a bunch of Google property adapaters. This is standard.
> 2/ Is my data safe? Doesn't use SSL, major red flag.
The PostgreSQL adapter doesnt use SSL (https://support.google.com/datastudio/answer/7288010?hl=en&r...). This is a showstopper.
> 3/ How easy is authoring? [EDIT] seems decent, see demo in reply.
You can see Felipe's demo here and make your own assessment. https://medium.com/google-cloud/showing-off-the-new-free-goo...
> 4/ Does it support pivots? Can't tell from the website or examples, red flag.
If you find an example I'd love to see it. My expectation at a bare minimum is a table view with a dimension down the left, a dimension across the top, and a measure in the cells. I looked through all the examples and did not see a clear example of a pivot.
> 5/ Can I model joins? [EDIT] it cant, see reply
It can't. https://news.ycombinator.com/item?id=15446616
> 6/ Does it support dashboard-wide filters? Many examples of this in the gallery
Most of the examples in the gallery use this feature.
> 7/ Does it support complex time comparisons? No examples, red flag.
Here's a couple very basic examples of what I'm talking about.
- Plug an TY date range into the dashboard filter. Get a view that shows you TY performance in that range vs LY
- Filter the dashboard using calendar dates, display using fiscal dates.
