Why burst into tears because someone you know, who doesn't want to communicate, doesn't go oh MIL darling, my best friend, hello, how are you, hope you're keeping well.
Projection and bias is rather visible when people post what they imagine the OP's expectation were and reveal how synthetic their imagining of those expectations is.
Especially in a context when typically what people prefer to being overtly and publically blanked in front of people they work with is more along the lines of...
Hi, how are you you ? - Good - Oh, fine thanks - See you
The DILs who are genuinely being mistreated by an awful MIL (as opposed to being a DIL-Who's-An-Awful-MIL-In-Waiting, cos they are probably less blessed in terms of empathy) are those best placed to understand why
- years of unearned dislike and background tension
-being regularly pushed aside and made to feel very unwelcome
-then being topped off by a public blanking so overt that the people who observed it were moved to comment upon it
....might result in tears shed.
Cost they know that the reality of shitty things being done on purpose to make somebody feel despised for an extended period of time is a horrible, unsettling thing to be on the sharp end of.
They also know that people in that position are not robots, they are hurt-able beings. With limits to how much rising above and internal OMMMM-ing they can do.
And they know there are times when the constant background tension of always being on the back foot will leak out.
If any of the DIL's reading could understand a fellow DIL having burst into tears when a ten year long campaign of sidelining was now leaking over into their professional life, to the extent that questions were being asked by fellow professionals, then they have all the empathy-tools and knowledge at their disposal when the roles are reversed and a MIL is at the sharp end of not exactly lovely DIL.
If somebody pulls a 180° perspective change when the roles are reversed then they are operating under a degree of bias that undermines the value of their opinion. Cos it stops being about talking through a fellow MNer's pressing issue and starts to turn into the OP being used by some posters as a proxy for their own MIL. Where she gets a kicking as pay back for the sins of another woman.
