I'm not a huge fan of Destiny - their approach to Christianity is very business-like. You follow this 3-step program and BOOM you're a Christian too. Rinse, wash and repeat. They focus on recruiting, talk the talk, and usually put on a good show - but it was very hard for me to find a deeper meaning in most of the messages.
However, this situation really doesn't seem that unorthodox. I mean, they bought the building in 2014 and the first thing they did was put their offices on one end of the building and the church on the other. Who couldn't look at that and assume they would eventually want to connect the two?
She already owns all of the equipment she needs. I understand she'd have to move it to a new place, but according to the article they're not charging her 3-4 months rent, so hopefully that helps cover most of the moving costs, and maybe some advertising cost to let folks know where your new place is. Many commercial rentals will buildout for their new tenant and build the cost into the rent over a multi-year contract, so depending on where she ends up there might not be any up-front costs for that either.
While it's an incredible inconvenience to the business, it seems like the real conspiracy in this story comes from having just the right pieces to make it a heartbreaker. An injured veteran being bullied by a big church (that certainly isn't the most friendly organization).
Hiring a lawyer will just cost her money that it sounds like she doesn't have anyway, and what is the end result? Best case scenario, she ends up with a landlord that obviously doesn't want her there. And worst case, she loses and has to move out immediately. Oh, and the lawyer still takes his cut of whatever is left of her business. And the paper can do a follow-up to document the tragedy.
