I'm not sure how a Chromebook could "wipe out the network".
In fact, if anything, I'd argue it's less likely to than a Window laptop since Chromebooks are so secure out of the box.
I bought one for my mother a few years ago, and honestly, not having to go over and clean up malware periodically, or ever do Windows Updates, or ever worry about her clicking on dodgy links on the internet has been a Godsend.
Unfortunately, even though I wish it was the year of the Linux desktop it's still not quite there yet for the non-tech savvy.
New devices are a pain, websites that don't work for whatever reason are a pain (since Linux penetration is so small, a lot of people don't test it), and overall the UI is nice for power-users but still inscrutably complex and unintuitive for the non-initiated. It's possible your mother has a knack for the UI though =). Which desktop environment did you use?
I admit, setting up the system can be a little time-consuming. But once everything is working, it is real easy to operate.
If there are any problems, I help.
And it's spelled "troll".
However, I'm still unclear about your main point.
If you're not talking about a "literal" Chromebook...what are you talking about?

Boss: Hey dabockster, I just bought this flashy new drone from this vendor we never heard of before. I had my doubts but he gave me a bunch of light up fidget spinners for my kids. Can you hook this up to wifi?
Me: Sure thing.
Hour later:
Boss: Why is the internet down?
Me: Your drone wouldn't stop pinging out main DNS server.
Boss: But it's expensive and flashy and SPIN CITY!
Me: facepalm

Note that didn't actually happen. But it's an example.
> Me: Your drone wouldn't stop pinging out main DNS server.
... you should fix your DNS server.
Anyway, this is all off-topic. I recommend that you stop commenting on a thread about Chromebooks about non-Chromebook issues, and spend the time learning how to deploy high-quality infrastructure, because your hypothetical boss is right.
