Tbf yes. They do something good for the planet. But I wouldn’t say choosing a different OS isn’t good for the planet either. First, you aren’t supporting companies that will burn this planet down without a second thought for a few million dollars. Secondly there are a few things on Linux made to use less electricity than Windows AND the fact it can run on older computers just fine means that there is less of a need for constantly upgrading this creating less computer waste. (Which something I and many others advocate for and a very solid reason to use Linux) but also merely for the fact that it is by far more ethical in a multitude of ways…
