TL;DR: Mattress company starts up wants publicity, finds startup bloggers and offer commissions. Mattress company gets kind of big and no longer needs reviewers so they cut them off. Reviewers find a new partner to the dance with and it turns out they like another mattress a little better than the original and let everybody know about it. Now the Mattress Company is pissed that another product is appearing on their good review, so the obvious choice is going nuclear and suing. Other reviewers have caved but one holds out, they fight back, but this is David and Goliath in terms of money and power. Original mattress now claims new mattress is actually fraudulently paying you tons to only like their mattress, tries to drag your name through the mud and then when all else fails they paid another reviewer of mattresses to buy up the one they sued, in return the new mattress ads get cut, and coupons to original mattress show up effectively making original mattress the best once again.

TL;DR for TL;DR: The Mattress company sued then paid a blogger to buy out the sued blogger to remove reviews with links to better mattresses.
