Not sure I agree with the premise. Amazon AWS services has plenty of scale as do many other private companies. Twitter raised almost $13 billion over many private funding rounds from venture capital firms before going public. That amount of money could have provided them plenty of opportunities to scale.

Twitter makes plenty of money. In 2020 reportedly they had revenues of around 3.7 billion dollars, and close to 1 million dollars per employee. They have plenty of income to support significant data processing capability. Their financials indicate they spent about 1.3 billion dollars for their IT systems and hosting.

In 2020 they included a provision for over 1 billion dollars in income taxes, which generated an on-paper loss for the company compared to prior years.
