If you start hawking stuff that isn't relevant or beneficial to anybody but yourself it will piss people off.
And public things are up for discussion, comment, criticism. And not everyone is nice. It's a hard pill to swallow. If your life is public you lose ownership of the commentary.
These two points raised by @MrsLister and @Spiney sum it up for me.
MOD and FOD have gained thousands of followers by speaking to people on a level and then, because of those same followers, they are now being gifted ludicrously expensive holiday villas that very few, if any, of their followers could actually afford.
Endorsing a £7k a week villa doesn't benefit anyone except MOD and FOD. Where's the usefulness? Where's the purpose? I guess if I was in the market for a £7k-a-week villa to take my family of six on holiday I might be glad they'd road tested one for me
Otherwise it's just them bragging.
Where once they were inclusive, now it's just alienating.
And yes, if you make your life public, people will, and are entitled to, form opinions and express those opinions. Whether nice or not.
You can't put it all out there and then be all 'thought police' and say no one's allowed to say anything negative about it.
