That's not how capitalism works; the weakest companies should be allowed to fail. The government can still lend to keep their workers alive, but what it's really doing in this crisis is keeping their stock price alive, which overwhelmingly benefits corporate insiders and rich people who own stocks. That's the opposite of how the corporate form is supposed to work—equityholders get all of the upside on a sunny day, so they're entitled to ZERO protection on a rainy day. It's risky to buy stock. Buy bonds if you don't want to shoulder risk.
The most frustrating thing to me is that the same companies who are asking for buyouts could have simply held excess cash, or raised their employees' wages, or invested in profitable assets—all things you expect companies to do under capitalism! But instead, they invested in stock buybacks, which means literally spending retained earnings on inflating their own stock price. Apple is a classic example: earnings has actually been flat since like 2015, but earnings per share has gone up because Apple has bought back $250B of its own stock in the last eight years or so. But at least Apple is solvent! The airlines, for example, are asking for a bailout in almost exactly the same amount that they have spent on stock buybacks in the last several years. It frustrates.
