Not all smart plugs are proprietary. You could even make one yourself with an ESP-01, a relay, and open-source firmware like ESP Home if you know what you’re doing to make it safe at that kind of voltage. If you’re overconfident in your ability to make it safe, then you’ve still got an untrustworthy smart plug at the end of the process, so it’s not necessarily a good idea, but it’s not proprietary.

Hmm that’s a good point. Never seen one for sale that I trusted though, and I did have a good look at one point.
There are many that can be reflashed with open source Tasmota firmware. Sonoff is one of the popular ones.
IKEAs Trådfri plug can be adopted into anything that supports Zigbee. Works out of the box with Zigbee2MQTT. No flashing required.
Don’t use wifi smart stuff. My house uses zigbee, so you have to be physically close to interact in any way. That really narrows down bad actors.
