People will deny this but this is the only real reason for doing that. The other reason is copying apple, which isn’t really another reason as apple removed it for the first reason. Fairphone just went the extra mile to claim that headphones are wasteful, in essence they’re making an excuse to cover up their reason why and also trying to force others to do it as well.
I know that this comment can be seen as insensitive but honestly, the OP is a terrible person who engaged in abusive practices in their community such as creating toxic posts, abusing their moderator powers to silence any criticism (downvotes included) towards them, and openly threatened the admins of the server because they stepped in and took action against the post which seemed to promote harmful misinformation.
When she was eventually kicked out by another moderator she decided to take to her alt account and tried to foster ill will against that moderator and get them removed. Which ultimately failed.
Recently she has deleted all of her accounts, at least all the ones that are publicly known likely to escape accountability for her horrible behavior.
