Might be switching to Chrome out of spite
Yep, looks like I'll be going back to Chrome as well. Bing has always underwhelmed me with its lacklustre search results anyway, and Edge is full of excess toolbars and pointless features, like the unwished-for tab grouping thing and the desperately slow and largely unhelpful Chat interface that tells me information I will have just learned from scanning the other search results that appeared while waiting for Chat to laboriously teletype its answer out one character at a time.
I'm not going to waste my time chasing one-point items to make Edge's browser market-share look better. Either make MS Rewards worthwhile, or scrap it, but at least have the decency to let us in on your plans, Microsoft.
