The more likely option than any of these excellent free options is going to be MacOS… just because your average user with even semi-technical inclination does not want to use LibreOffice Present; they want PowerPoint.

I have just seen this first hand with my significant other: they are very technical and more than capable of it, but have zero interest in learning Linux and instead just bought a MacBook on Black Friday specials when their 5 year old HP laptop finally got too annoying to use.

Well, I didn't mention MacOS because it is not installable on the author's win10 computer.

Also, MacOs is as difficult to learn as Linux is for someone who never used it. Resistance to change exist in all directions.

Most people are fine with the web version of Powerpoint.

I have had good experiences with Proton. I pay for the business tier so that I can manage multiple domains… but that’s not your average setup.

Literally my only complaint is that the new-ish vanilla SMTP service does not play well with systems like DMA or Postfix, so I have issues using it for cron emails on my servers.

Everything else has worked pretty much perfectly since I migrated over.

Edit: I echo other commenters though, get your own domain regardless of where you host it. That way you can always pack up your toys and go somewhere else if required

One point twenty one jigga-watts anyone?

What is obvious to you and I is not always obvious to everyone else

I believe it has a lot to do with the fact that new Outlook operates on email in their cloud, and that means they can … process your email as they see fit.

Remember that adding an account to new outlook means all your email gets uploaded to O365 servers. It no longer interacts locally. That includes external services like Gmail etc.

As someone who designs load-balancer solutions for a living I cannot agree with this more.

I likewise assume that all servers are insecure, always, and we do not want them exposed without a sane load balancer layer.

Your server was probably not made to be exposed to the public internet. Do not expose it to the public internet.

Does anyone else notice how similar that is in spirit to what a malicious actor would look to do after gaining access to your network?

Or how a malicious actor inside your network would follow exactly this plan to do malicious things without your knowledge...

True, if you assume a table here has 1 column. If you are printing multiple columns you print a full row at a time.

And that in turn is all running on a nice layer of CentOS 6

I rewatch many movies quite often. But the ones that really stand out, in no particular order...

  Wargames
  Jurassic Park 
  Evolution 
  Unstoppable 
  Lord of the Rings
  Die Hard 1, 2 and 3
  Alien 1, 2 and 3
  Back to the Future
  Ghost in the Shell (basically all of it, mostly seasons 1 and 2)
  The Martian
  Tron 1 and 2
  Anything by Miyazaki, but Howl's Moving Castle even more so

Or Broadcom...
