On the question why ‘unsafe apps’ check this poll that was conducted here. The consensus was that users want unsafe apps. The applications on Apps Installer are requested by users. It is not mandatory to use Apps Store you are free to use FDroid or any other app store you want. We have a plan to come out with a FOSS only ROM this year.
Using Maps or Weather was done because of lack of better options available in the FOSS world. IF we find better alternatives we will happily switch over to using them.
About wikipedia I wrote the original /e/OS related wikipedia article. I do not hide it in fact on wikipedia I use my own user name and do not hide behind a pseudonym…would have loved to use manojnair but the name was already taken!. You can even get my details on my user page. That includes my name and even my photo if you do some clicking around the page! I wrote that at a time when I was volunteering and did not take any money for that. This is also mentioned on the page. There was a discussion if the page should be retained or deleted and that topic attracted a number of /e/ team members. We were told not to make edits as that constitutes a violation of wikipedia rules. Post that warning I gave up any edits on any /e/ related pages.
There is a full fledged campaign to discredit /e/ and its team members by getting to ban us on wiki or delete our pages and it is being run by the xyz site folks.Good luck to them !
Now I am not sure if that comes under wiki’s policies but I think if writing in favor of an organization is wrong so is writing against or vandalizing pages of that organization by a group which even maintains a website dedicated to hate /e/ topics! Anyway that is for wikipedia to figure out.
All I can say is use your own discretion and try to figure out what is right and what is wrong. Do your own research and find out what suits you and follow that route.
