@joepie91 It has never shown up opened for me, so I do assume some tampering is involved...

@GLaDTheresCake There have been some wider reports of tampering with these magazines in the mail, and I've had inexplicably delayed issues before, as well - and it's not the first one that's arrived opened either, with the glue strip being sticky but not closed, suggesting it was probably once closed and then steamed open or so.

It seems pretty clear to me that some sort of tampering is happening, and the fact that they are not imperceptibly resealed (which isn't exactly very difficult) suggests that there is very much an intention to communicate "we are watching your mail".
