They did misuse their place as the company that owns the software platform that runs on 75% of the mobile devices to do this though. When they launched google pay, it was called "tez" (not sure what it means - probably hindi for speed), only to be changed it to google pay so that when people search "pay" for the paytm app that was the market leader in this space, "google pay" comes first. They did have much better UX than paytm and bhim upi (government provided app for UPI interface) apps, but they still had to rely on unethical app renaming to corner the market.
IIRC it was already a hit as Google Tez, probably because it is a much better name. The google pay re-branding was done when it had already proven to be a huge success, probably with a long-term goal of merging it with the international Google Pay.
