As an IT professional, I can know that operating Zoom (out any other similar service) is orders of magnitudes easier than an airline.

For one, having catastrophic bugs means to send a "sorry" mail to your users. And maybe fix them.

Such bugs on a plane mean death of people. It is similar to suddenly not having wings. And they are back, but half of the cabine is gone. And suddenly no more plane, you are kindly asked to flap your arms.

But all these difficulties means airlines truly deserve to be mistrusted as an investment vehicle, and to this direction Warren Buffet recently pulled out all investments from the airline industry. So it's really not that comical that airlines are where they are, especially during COVID.

Plus it seems like part of the business model of airlines is lobbying for government bailouts.

And less riskier too. 1 day downtime for Zoom will be a blow in their business but will be backup the next, a few flights crashing in day and the rest grounded will put an airline out of business.
