I could buy this argument for 50NL+, but not 10NL.
There are so many rec fish playing 10NL or 5NL that worried about being "exploited" is unnecessary.
If our villains are willing to shove pre with 99+ hands because they put us on AK then by all means, 4-bet shove away. If our villains are likely to fold everything but KK to a 4-bet preflop then we should be flatting their 3-bets so they retain the initiative and will likely shove 88% of all flops that don't have an Ace...
Basically, for the most part, it's villain dependent. And since so many villains who 3-bet will call a 4-bet we can go ahead and 4-bet most of the time. Just make sure you size your 4-bet so they more or less have to call. If you can get stacks in do it, otherwise, just 4-bet between 1 - 1.5 times the 3-bet amount plus size of the pot.
