First of all, the 5th amendment only applies to individuals, not entities like corporations. Second, it's main purpose is to not incriminate yourself - sharing business plans is hardly incriminating in itself (unless the business plan is specifically to commit a crime, but that would be dumb... Oh wait).
To me this feels like that Meta is trying to simultaneously measure up the market by making their competitors give out business plans that, frankly, are none of Meta's business, while also tying up smaller companies they feel threatened by in legal battles, as to drain their resources and run them into the ground (or, just a more appealing position where Meta can buy them up). And the latter isn't really new - I mean, Amazon pretty much "fired" mid-level executives and "placed" them at various competitors with the sole task of driving down the valuation of the competitor for easier purchase.
Either way, this kind of abuse of the legal system is disgusting, and even if the subpoena has legitimate reasons, it places an unfair amount of responsibility on an otherwise uninvolved party. The federal government could compel your company to produce an employee who can jump over a 5m wall, that doesn't mean it's suddenly possible.
