That's one way to look at it. I used to look at paid VC-funded services like that. I no longer do as I've observed services I paid good money for get more expensive much faster than inflation and decrease in quality and features at the same time. It's one reason I self-host many services I used to pay third parties for. I now look to alternatives from the get go and derisk existing dependencies. To be clear - profitability isn't merely the only problem. The ownership and its profit growth strategy (and expectations) are. Those are not the same in a decades old ISP and a VC-funded startup.

Merely being profitable today isn't a good predictor for stable prices and function over the long run for VC-funded services. I'm not planning to do major surgery to my setup every few years as yet another service shits the bed. The workstation/server where my self-hosted services run has last been reinstalled in 2014. Most of my config-as-code was written in 2019. I support a few families with this and I aim at maximum stability with minimal maintenance. So I use open source whenever I can and I often pay for development. I only integrated Tailscale in my setup because the clients are open source and because there's an open source server option.

I'm not saying to people - don't use Tailscale. In fact I often recommend it to new self-hosters. But I do that because there's a way out. So here I'm reminding people who care about a way out to check if this feature is escapable. :D
