Where the reports disagree

1Which ETF was the primary driver of the week's outflows

BlackRock’s iShares Bitcoin Trust (IBIT), the largest spot Bitcoin ETF by assets, was a primary contributor to the outflows.

What would settle it: Fund-level flow data from Farside Investors, SoSoValue, or the ETF issuers' own daily creation/redemption disclosures.

What to make of it

Treat the overall weekly outflow figure (~$390M) and Monday's ~$144.7M outflow as established since both outlets agree; do not treat claims about which specific fund (IBIT or FBTC) drove the outflows as settled until fund-level flow data is checked directly.
