> not to mention who have significantly diversified their revenue from their original business lines

Both Microsoft and Intel very successfully diversified their businesses at various times. I'm not sure you could have named two other tech giants that did a better job of diversifying away from their original product lines (which was not Windows for Microsoft, and was not microprocessors for Intel).

Microsoft didn't start out as an operating system company, they diversified into that business. Then they successfully diversified all over again. Windows dominated Microsoft's business for about 15-18 years. That's no longer the case. All profit from Windows could go away tomorrow and they would still be earning around $15 billion per year in net income. They're now a heavily diversified technology conglomerate.

Intel was a business initially built on memory chips, which were their first products. They did an extremely good job of diversifying; had they not they would have disappeared with the memory business.

"While Intel created the first commercially available microprocessor (Intel 4004) in 1971 and one of the first microcomputers in 1972, by the early 1980s its business was dominated by dynamic random-access memory chips."
