Obviously, because someone didn't want the public to find out. This is not uncommon - in fact in is basically the norm in any industry. People cover their asses, so they don't get arrested or sued. Actually, two of the largest areas of law, consumer protection, and public health law, are basically about going after corporations and government agencies that conceal information from the public regarding accidents, mistakes, and other hazards caused by these corporate and government entities. It should not be surprising that a company or government agency would want to lie or conceal what happened if it made a big fuck up. If you weren't an unedcuate brainlet, then you would probably intuitively understand this, and even know of some historical examples. A very recent example is the Flint, MI water crisis, which has been concealed by water companies and the federal government, but which has been widely identified by numerous independent scientists. Again, you're obviously not someone who is is very educated or intelligent, and you must not follow politics.

Another example, which you can look up on your own was the Bhopal incident.
The biomed and biotech establishments don't want people scrutinizing the NIH, the Wuhan Institute, GOF research in general, and many other risky and ethically questionable forms of biotech and biomed research that are becoming more common today (e.g., a lot of "neural interface" technology). If you don't understand why this raises serious practical and ethical concerns, then you need a better understanding of basic democratic principles, the public well-being, and the concept of informed consent.
