Nifty - useful for quick testing tasks.

The concerns though are the sustainability - if instances are paid for and not free tier + bandwidth, it could not be around for long, particularly if it gets abused.

Also, privacy/security - there is no guarantee that instances are destroyed/erased after use and won't get assigned to someone else or logged into. Probably don't want to put private code/IPR on there just in case.

For quick commands (eg, testing a firewall setup from the outside or checking something from an external ip) then it's very cool indeed.
