Wasn't HIBP a single person.

So presumably a checking system could have been churned out by, being generous, a team of 6 on a mean-average $100,000 wage. Lets say $1.2M per year (doubled to account for facilities, etc.) as a top end. Realistically surely that's a couple of months work for such a team?

Looking at the Send github (https://github.com/mozilla/send/graphs/contributors) it's essentially 2 people, about 1.5 person years in the commits.

The first and fourth items you list sound like absolute white elephants that management should have allowed only as "we'll give you a full time dev wage for it and spare facilities, show us what you can do and we might take it on".

So, what have we got left $240M?
