I know we should wait for actual facts to be released and not automatically be sold on "announcement of announcements"; and while this is most likely probably not directly related to bitcoin/cryptocurrencies at all, I'm just sharing this just to put things in perspective.
If a certain website/service that has this much users(more or less 1.2 billion based on the Tweet) are susceptible to hacks, what more the exchanges that you're unnecessarily leaving your coins in?(daytraders are an exception).
And I don't care if you're using big exchanges like Coinbase or Kraken or Binance or whatever. If anything, they're actually bigger targets for hackers.
"Not your keys, not your bitcoin."
For speculative purposes(services with number of users closest to 1.2 billion based on quick Google searches):
Facebook: 2.4 billion users (source)
Apple: approx 1.4 billion users (source)
Gmail: 1.2 billion users in 2018 (source)
YouTube: 2 billion monthly active users (source)
WhatsApp: 1.5 billion active users (source)
Microsoft Office 365: 1.2 billion as claimed by o_e_l_e_o, also Microsoft Office 365 went down yesterday[1][2][3]
It's pretty much a guessing game right now, but it looks like it's probably Microsoft Office 365.
