Tech - So, Bye Bye ESXI?

So a bit of a clickbait title I know... So as I'm sure unless you've been living under a rock, VMware has been bought out by Broadcom. This has created a panic over the pricing increases moving from a perpetual to a subscribing-based pricing model. But

Okay, this one once had me stranded. It could be a pointer or preventive maintenance! Typical for European cars fuel is delivered from plastic fuel lines, in my case this is no exception. But as this might be an easy cost-saving option, it can lead to air entering the system.
