I've heard from some large event organizers that EventBrite is taking similar measures: delaying payouts to event organizers until the event has concluded. I heard from one organizer that they were told by EventBrite that they were not going to see a payout until 2021 for their Labor Day 2020 event.
If that's true, it could be an excuse to financialise the money. Let it earn 5% while you don't have to pay it out. Or worse, use it for opex in a big ole ponzi scheme style busines!
Also, to be noted, Github was a Rails app since long before there was native support for adding foreign keys. I've worked on a lot of large monorails that were created in Rails' early days and none of them have foreign keys.
Aaaaaand that's why I no longer use Amazon SES for transactional mail for signupforms.com. It is frequently used by mass-marketers, which means my transactional email was frequently being dropped by some email providers because of SES's poor deliverability.
Author here. I've noticed the opposite. All things being equal (email content/subject lines etc), my opens, clicks, etc.. all have increased since switching to SES. Not sure if an anomaly or what, but that's my experience.
Seriously, doing bulk emailing you find that mail services are often the dustiest, cobwebbiest things on the internet. I swear some of these things have been sitting untouched for literal decades.
