'unwanted guests of tech' is the definition.
I can't tell whether this defines the answer.

'billionaire eating cold bacon' is the wordplay.
'billionaire' becomes 'Gates' (tech billionaire Bill Gates).
'eating' means one lot of letters goes inside another.
'cold' becomes 'C' (eg on taps).
'bacon' becomes 'rasher' (I've seen this before).
'c'+'rasher'='crasher'
'gates' going around 'crasher' is 'GATECRASHERS'.
