The legal perspective is that Parliament decides the law of the UK. If Zuckerberg doesn't turn up, then he is snubbing the very people who decide the future of Facebook UK.
it also sets a precedent for other (european) countries to try the same.
If he doesn't show up their, they might take this "up the bloc" so to speak, and make this an european issue.
Does facebook want that on it's hands?
But that should not have any impact on cooperation in such areas where the U.K. and the rest of the EU have a long history of friendship.
Facebook, as well as Russia’s murders and chemical weapons attacks, are a problem for all. The U.K. should and will get the solidarity of all rule-of-law countries, both as a matter of friendship and self-interest.

The risk for Facebook is that the public are increasingly frustrated with big companies not paying their fair share of tax. Some people will say "but they're only paying what the law says they have to pay". Those people are failing to understand the British cultural value of "not taking the piss". Not attending would be saying "FU", and that's likely to add to the pressure to make these large companies pay more tax.

Historically, those found guilty of contempts could be fined or imprisoned, but those sanctions have not been used by the Commons since 1666 and 1880 respectively. For all sorts of practical, legal and constitutional reasons, it is highly doubtful that the modern House would seriously consider this.

The only real impact a government can have, cutting Facebook access, even in the direst circumstances, is rarely a smart option.
Is this accurate? The House of Commons briefing paper on Select committees: evidence and witnesses[1] describes the power as:
> In general a select committee with the power to send for persons, papers and records may summon any person within the United Kingdom jurisdiction as a witness.
