This is true, but you do get some corrosion between dissimilar metals; I imagine that the "pretty" anodizing helps deter that to an extent. I'm not sure I would use loctite on a wheel stud myself, let alone the red stuff; if anything I would use the weaker blue because it can be disassembled without heat/excessive torque as you pointed out earlier.
SpiderTraxx builds spacers, hubs, and other components for racing, crawling, ect. vehicles that compete in highly public venues. I highly doubt they'd purposefully design something to be weaker when they have possibly millions of dollars in customers who rely on, and brandish their product with confidence that could easily dissuaded by a poor product.
