Private companies have absolutely NILL reason to protect your data at their own expense. Particularly if you have not given an option to give it to them. And equally private companies see that cybersecurity costs money and doesn't earn money, so it is a clear and easy thing to "cut".
fun fact, google chrome spell check doesn't know the word cybersecurity nor spellcheck (the verb!) nor NILL, like seriously, how can it not know nill ? Even if it didn't know the modern use of the word, nill is a perfectly good word!
