That depends on your defenition of easy.

If you have more than one to crack, you can probably try a few of the
more violent methods (applying a high vpp >14v and un-programming the
code protect bit).

The 16F84  is not really any easier to read than the other PICs, it's
just that its use in the satellite TV industry prompted hackers to
quickly break into it and modify settings for free channel access.

The newer revisions have made it much harder to break, but no matter how
much protection you add, another person can always break it.

The real questions are:
Is what I have valuable enough for a person to spend a large amount of
money and time on to break rather than designing it themselves?
Is it worth the extra cost to me to build in other systems which will
prevent their access to the code?

Only you can really answer that.
