Another thing I would echo here is that you don't necessarily need a CMS / WYSIWYG editor to run a great blog. A tiny script that dynamically compiles your markdown flavour of choice and has a nginx reverse proxy in front of it will be able to survive a reddit frontpage hit on a $5/mo vps, and it will be dead simple to set up.
If you're looking to move off Medium, give it a try. If anyone is interested I'm happy to share the mini server I wrote to compile pug aka jade / stylus, which is what I use for my blog.
At least from my own experience, my own website is hosted on a simple $5/mo DigitalOcean droplet with a simple Flask backend that basically just converts Markdown to HTML and generates index pages and RSS and embed metadata and such. It's been completely fine with the surge of traffic from Hacker News; barely broke a sweat. CDNs only make sense imo if you're consistently having Hacker News levels of traffic.
True, but the point of the article was to avoid centralized providers as you may inadvertently be shadowbanned. I have much more faith/trust in Github than Medium, but nonetheless it still suffers algorithmic approaches to content.
