Yeah, I also hate back-button hijacking. I suspect some websites do it to artificially force more page views for ad revenue. Try a long-press on the back button to view the history for that browser tab and click on the most recent page you think won't redirect.
Can't speak for OP, but I took a maybe ten-year hiatus from Minecraft and came back to find the were so baby more block types that it clogged my inventory and I felt overwhelmed and just stopped playing again.
