I'm in favor for it but I think it would be too difficult* for you guys to implement with the right UI'n'all with the current task force, also https://send.firefox.com/ exists - not quiet as private and secure as OnionShare but quiet good for a browser thingy.
* : difficult in the amount of work, and not with regards to your know how.
Actually OnionShare for Android doesn't exist yet, so contributing to the OnionShare repo by making one for Android would be a much better use of time IMHO (unless Micah Lee has no clue about Java).
It will only be launched when the user wants to share some files, it's unclear how an attacker has much advantage here vs with classic OnionShare (they're the same I think).
and include OnionShare with it's ADD_ONION backdoor. /s
What? Do you know what all those words, i.e. "include", "it", "is", "ADD_ONION", "backdoor"...etc mean? I can teach you right now if you don't.
