Why are companies upset about Georgia wanting to secure their voting system?

Prove "most votes were not legit". The trump team had a chance to prove it over 60 times in court. They had no more credibility than you w/ your opinionated accusations. 

The changes Ga. is making include limiting resources in targeted districts that make it harder for certain people to vote. For example, waiting hrs. in line.

They were 100% legit and company's realize that fact

Only ******* morons say they were not legit

Because most of the changes have nothing to do with securing the voting system.

They are taking power over elections away from the Secretary of State (which would be fine if they were going to a non-partisan official, but they are simply replacing one partisan official with another) merely because the Secretary of State followed the law.  Likewise, they are giving the State Election Board the authority to temporarily strip local election authorities of their power over elections.  Both changes are about power, not securing elections.

They are also making rules about giving out water and food to people waiting in line to vote.  While it is permissible to bar electioneering in close proximity to polling places, there is no distance limit on this new statute and it goes beyond banning electioneering.  (Of course, the simple solution would be to expand the number of voting locations -- a minimum number of polling places based on the population of registered voters -- to reduce how long people are waiting in line to vote, but that is not on the agenda.)  

And, contrary to what you may have heard, multiple reviews in Georgia have determined that the votes were legit.

Because it makes it harder for illegals to vote.

And also black people because according to blue, blacks are too dumb to figure out how to use an id apparently

Most companies are of the opinion that a secure voting already exists and that Republicans are trying to dismantle it.  Most of the votes cast in Georgia were legit and Trump lost.  Worse, in the election two months later, Republican lost the Senate.  No evidence has been present since to imply that the contest would have been different.

They recounted THREE TIMES, Chud.

Trump lost, Snowflake. Get over it.
