There's no suggestion. There is currently no way a search engine can be a viable modern business model and a good tool at the same time. It could potentially be a good business model and a decent tool even with ads, but only in a world where we accept that things can't grow forever.
My boss once asked me to take a look at her computer that was super slow and barely functional, and the thing that surprised me the most was that she had been running Chrome without any adblock since ever, and when I asked her about adblock, she answered: "adwhat?". Mind you that she's still a millennial, and only a few years older than me.
It's not as bad as people here are making it out to be. It actually might even be an improvement. It's only for the all apps tab, and it organizes apps by their purpose, and you don't have to click the folder to expand it and then click the icon, as you can just click the icon and it will launch it. I've been using Windows 11 since it came out, and the all apps tab is something I have barely ever used. All my important stuff is neatly organized in one single tab of my home star menu screen, and anything that is not there I'll just look it up with search.
Let's not make them a business. Search Engines are fundamental core services for the modern globalized and connected world. It's just like your post-office service. Make it an internationally owned and funded non-profit organization with open-source and the goal of enabling the unrestricted sharing of knowledge over the internet.
