SAXON'S WAR ON HOMESCHOOLERS?

Linda Schrock Taylor smells a rat with homeschooling curriculum stalwart Saxon Math:

I have communicated with sellers of homeschooling materials who explain that Harcourt refuses to sell them any hardback books, hinting of some contract Harcourt signed with schools. If this is true, the contract supposedly prevents H.A. from selling the previous hardback editions to homeschoolers. If such a contract exists, it was a ridiculous decision with grave implications....

...[A] decision to restrict sales would make sense if the following rumor is in actuality a truth: that Saxon's goal may be to dumb down the homeschooling children with these new materials. In light of the suggestion of a contract to restrict sales, this additional tip/rumor causes me to wonder whether state schooling could be pressuring Saxon to harm homeschooling in hopes of compromising the academic progress that homeschooled students are making; of putting an end to homeschooled students excelling as publicly schooled students fail.

If Saxon has sold out under their new ownership, other options will appear. Homeschoolers are a resourceful lot. But why would Saxon actively seek to alienate what has been a segment of its business that has given it nothing but loyalty and support?
