Personally I like open source & I like paying for software (hopefully I pay for FOSS by using, bug reporting & sharing). I’ve no problem tweeting from an iPhone I paid for. More problematic Is how I “pay for” twitter.
Definitely part of it. But I think it’s also the culture of these digital tools. Free to use for teachers. And they offer and promise a lot. But, ethically, this is incredibly problematic. Says the man currently tweeting on an iPhone! Feels like there was more open source before
