Seriously? As a user of their service I'm glad to see them offload an extraneous expense to someplace that's better equipped for the service provided.

After evaluating this situation further, I felt further comfort in knowing there's an added level of authenticity to the post. They could have signed it with a GPG key which would've been nice, but not only would their core site have needed to have been comprised but also their medium account in order to deliver this news. Should this have been a security incident I would have been comforted by these additional ID confirmations.

Even a custom domain on Medium would bring it clearly under their brand (e.g. if this submission didn't have many comments I wouldn't have clicked it, since the title and medium.com signals "low-effort article by someone trying to make some political point", not "company blog"), while from a technical perspective also giving them the option to move later to a different platform without breaking their URLs.

Most companies don't regard brand-building and SEO as an extraneous expense. I'm sure Coinbase has spent their share of money on promotion. I'm also sure they could host a blog, or have someone else do it for them (does Medium have a self-hosted or custom domain option?)

They do have a blog at blog.coinbase.com
