Sundar Pichai did not "usurp" the previous CEO of Google. He was appointed as the CEO of Google on October 2, 2015, succeeding then-CEO Larry Page. The appointment was part of a larger restructuring process at the company, which led to the formation of Alphabet Inc., a holding company that serves as the parent company of Google and several other subsidiaries.

Pichai's appointment was widely seen as a natural progression in his career at Google. He had been with the company for over a decade, during which time he served as the Vice President of Products, overseeing the development of key Google products such as Chrome, Google Drive, and Gmail. As CEO, he has been credited with helping to lead Google through a period of significant growth and innovation, and with helping to position the company as one of the world's leading technology firms.

In short, Sundar Pichai's appointment as CEO of Google was the result of a planned succession process, rather than a usurpation of power. Pichai was selected to become the next CEO of Google on August 10, 2015, after previously being appointed Product Chief by CEO Larry Page. On October 24, 2015, he stepped into the new position at the completion of the formation of Alphabet Inc., the new holding company for the Google company family. Sundar Pichai became CEO of Google on August 10, 2015, when the company underwent a major restructuring, becoming a subsidiary of Alphabet Inc., the newly created holding company. As part of the restructuring, Larry Page stepped down as CEO of Google and became CEO of Alphabet, while Sundar Pichai took over as CEO of Google.

It wasn't a case of Sundar Pichai usurping the previous CEO, but rather a planned transition as part of a larger restructuring of the company. Pichai had been with Google for many years, and was a well-respected executive, having played a key role in the development of Google's Chrome browser and Android operating system. His appointment as CEO was widely seen as a positive step for the company, as he was seen as a capable leader with a strong track record of delivering results. Your use of the word "usurp" implies that Sundar Pichai took the position of CEO illegally or by force, which in this case is not evident. Pichai was selected to become the next CEO of Google on August 10, 2015 after previously being appointed Product Chief by then CEO, Larry Page. On October 24, 2015, he stepped into the new position at the completion of the formation of Alphabet Inc., the new holding company for the Google company family.
Indications suggest that there were constant differences of opinion between Larry Page and investors as well as management which would be a recurring theme during Page's time as CEO, this would see him step in and out of the CEO role multiple times and ultimately may have been a contributing factor that led to both original founders Larry Page and Sergey Brin opting to leave the company to pursue their passion for innovation outside of Google.
