Why Google caved to Australia, and Facebook didn’t

  Why Google caved to Australia, and Facebook didn’t A corporate giveaway might help the platforms save face — but it won’t save journalismI think Facebook basically did the right thing, and Google basically did the wrong thing, even though Google had a much tougher call to make. Today, let’s talk about why the tech giants made the decisions that they did, why Australia’s shakedown is rotten, and what’s likely to happen next. (If you didn’t read my piece on the subject, it offers a lot of useful context for what follows.

The ventilation systems in buildings present a high risk of the spread of the coronavirus. That's the conclusion of a preliminary report released Friday in Western Australia. He had been dispatched after the detection of a new case of coronavirus at the end of January, the first in ten months in this Australian state, which had caused the confinement for six days of the city of Perth. These discoveries are worrying, while other "mystery" cases have appeared in closed places in several Asian countries, where the hypothesis of airborne transmission of the virus is most likely.

  Facebook's news blackout: Why folks outside Australia should care A proposed law in Australia could be the first of many around the world."Assuming this draft code becomes law, we will reluctantly stop allowing publishers and people in Australia from sharing local and international news on Facebook and Instagram," Will Easton, who manages Facebook's Australia and New Zealand operations, said in an August blog post.

However, he had followed the health protocol to the letter and had never been in direct contact with the people confined in this hotel.

Therefore, the most likely hypothesis is that the virus has circulated in the hotel, through its ventilation system and that it can therefore be transmitted by air. A track also considered in Melbourne, where recent cases, also appeared in hotels dedicated to quarantine, have not found other explanations.

Same phenomenon in several Asian countries

Airborne transmission of the virus is also envisaged in several Asian countries, where contaminations, which have occurred in restaurants, public transport or even in apartments in the same building, cannot be the result of people-to-people contacts.
