I’ve always been hesitant to use a service which ships thing’s I write back to home base. Instead I used Microsoft word, which turns out does similar.
I would not use anything closed source and bloated as Word. I wrote my BSc. thesis in it in the 2000s. Could not open it correctly anymore after 5 years. It took ages to open.
Switched to vim and latex for my master and phd thesis. Never looked back ...
