or... maybe this is just a fun side project they whipped up as a joke? Some side project for a resume?
Just look at OP's comment history, one example:
> I absolutely love making chrome extensions - my very first one was creating an extension for tinder.com that would swipe left on anyone with the first name Chad
All they require here is your name and email, and the recipient's name and address. Both are (probably) public somewhere and in combination are almost certainly still worthless (or certainly worth less than the postage they're giving to you for free)
Why not just make a pdf or a copy paste version? I get suspicious when extra work is done to make worse ux; my assumption is that it rarely happens without a hidden incentive.
I'm not sure if they changed it after your comment, but right now there is clearly two options. One where you can get a google doc and just use theirs as a template, and one where they send it for you.
