I thought that as well. However, isn't Russell's infamous for taking Albon out (albeit in Sim racing).
I doubt very much than F1 team would be making decisions based on any of the sim racing happening right now. They'd have to pull a Pagenaud for it to even register and even then I doubt it would sway a decision.
I doubt Hamilton would want a young hungry driver nipping at his heels, with the potential to jeopardise his championship hopes. I expect to see Bottas stay at Mercedes as long as Hamilton does.
Maybe, but Mercedes and Hamilton don't have precisely overlapping aims. Many people talk about Russell as being potentially a Verstappen/Hamilton level talent. The last thing Mercedes will want is to see their promising future star blunt his career trundling round with Williams. They'll want to get him into the top seat, let him learn from Hamilton, and take the lead when Hamilton begins to fade or decides he wants a final challenge elsewhere before leaving F1.
