Essentially with Databricks making Delta open source, you can move away from Databricks to EMR or Presto (with their own optimizations) without incurring a data tax. You're also able to move between cloud providers at ease as data sits in low cost buckets.

They must do. But if you've been in this area for long enough, I'd put my money on Databricks, if anything, because of their open source integrity

They could in principle. GCP, for instance, does do that. So does HP. And Databricks don't mind that as they have a strong open source legacy. But that takes away the proprietary lock-in strategy of Snowflake.

So much to read. TLDR; Databricks still holds the world record and they beat us on price/performance

You'll need to revisit this again. In the last two years Databricks has built a lead and a bigger moat. They're essentially nice chaps with a huge community backing them. And we all love their open source tools which essentially powers not only their big data platforms, but everyone else's too (AWS, GCP).
