every piece of professionally-made electronics you have ever purchased within like the past 20 years uses non-leaded solder, I repeat this is a skill issue
I repair lots of equipment and pa speakers made after the rohs unironically always have bad joints because so may of the components aren’t designed for high vibration environments (it’s a subwoofer, it’s like literally its own source of high vibration environment! I’m going to go insane and get arrested for doing okc to ev and behringers design departments!)
It's also by design. Repeated heating and cooling cycles in consumer grade electronics eventually lead to micro fractures in the solder, which will make it so you have to replace it the future. Zero fail spec electronics (think space craft, aircraft, high heat applications, or other applications that would cause mass casualties if they fail) use leaded solder because it does not fracture. In it's intact form inside of your phone or computer, leaded solder really is harmless.
