Hey, they said it themselves now, don't blame me.
If we would write this on our own, some people would object vociferously, and make a ruckus. So don't take it from us, take it straight from Chabad-Lubavitch themselves.
Chabad-Lubavitch has had a big stress on PR for decades, if not longer. R. Yehuda Krinsky was hired by them way back in the 1950's, davka to have a native English speaker on staff for PR purposes. Over the years, the operation has grown greatly, and now they churn out oodles of material all the time. Not just print, like when R. Yudel started, but audio, video, digital too.
This fools too many naive people. They see all the mentions of Chabad-Lubavitch and their emissaries in the media, but much less mention of others, who don't have such giant PR operations publicizing their every move, so they are duped and deluded, and come to believe that Chabad-Lubavitch are basically the only ones out there, doing various mitzvos around the world, doing outreach, etc., etc. While so many other Yidden are doing various mitzvos, kiruv, chesed, etc., etc., modestly, far and wide, without fanfare, following the path of Chazal, who instructed us that אין לך יפה מן הצניעות, those without big PR machines are invisible to too many, even to some clever and affluent people who should know better.
Chabad-Lubavitch has various tactics to get themselves in the news. For example, when there is a natural disaster, say a hurricane or earthquake in some distant land, they have it is publicized that their shliach in the area lifted a hand to help some people. They prefer such free advertising, as the price is right, and it makes a "Kiddush Lubavitch" (a term they use for good PR, their version of a Kiddush Hashem, lehavdil).
Anyway, the brief video in the post linked to above (there is a much longer JEM video on the topic as well, but it requires payment to view) shows that it is very much a planned and deliberate strategy, and that it came all the way from the top, from the last Rebbe himself. Interestingly, at other times the Rebbe instructed that things be done מיט א שטורעם, loudly, which seems to be a similar or identical idea, albeit utilizing a different expression.
May הקב"ה help us grasp the the true nature of things, and not fall victim to deception.
