Not related to this and not a user (yet?); I saw they do have a compare page [0] with both postgres and timescale comparisons.
"Time series databases like InfluxDB or TimescaleDB are unable to handle many IoT applications by themselves—if they require metadata operations, for example. They often need to work in combination with an RDBMS, duplicating maintenance efforts and costs. Besides, their performance is usually optimized for single-node processes."
This statement is true for InfluxDB (which doesn't store relational metadata, and where multi-node is an enterprise paid feature), but not for TimescaleDB. TimescaleDB is built on PostgreSQL, so it is in fact an RDBMS and allows you to store relational data alongside time-series, plus it is now distributed (multi-node), and this distributed feature is free [0].
Which is why we have some really large IoT deployments, including at Schneider Electric, Siemens, Bosch, Northvolt, and many others.
(I've met some folks from Crate and they've all been friendly, so I'm sure this is just an honest mistake, but it is incorrect nonetheless.)
I have not seen a proper TimescaleDB vs. Crate comparison, but at a high level, TimescaleDB is a relational database for time-series, ie "Postgres for time-series", so most developers find it really easy to use (and performant). Also, we just made all of our enterprise features free, so TimescaleDB is now completely free to use.

However, we still need to defend our use cases... CrateDB has been distributed since the beginning, and it is a very mature technology in this regard. The page you mention is a high-level comparison indeed, but we do talk a little more about Timescale in this post:

We worked on this with your team actually, which in fact assisted us in configuring Timescale. They were great -- but CrateDB performs better here.
We've been also in touch with your team with regards to more comparisons with Timescale... As in order to be fair, we wanted to share everything in advance. This is not a Crate vs Timescale war! Still, we believe CrateDB is amazing and we invite everybody to try it: https://crate.io/download/
