Illegally bought or buried them?
1) FTC approved all the mergers. So, it is surprising that they'd say that these were illegally bought.
2) Facebook seems to be operating all key acquisitions (Instagram and WhatsApp) as separate products and hasn't made their usage conditional to having a Facebook account.
This is re-writing history and it is just as dangerous when the FTC does it as it is when a political party does it.
