BY is compatible with BY-SA. That is, you can incorporate BY content in an SA
work.

[I have an irrational fear that "compatibility" will become such a shibboleth
that any "incompatible" license will have to be made "compatible" for the good
of "compatibility".]

Because it breaks the deal. Like putting it (or NC-SA work) under an ND 
license.
As Terry says, it violates the sharealike and is more restrictive.
